Voss has come under increasing pressure following the latest in a series of second-half meltdowns by the Blues, who surrendered a 22-point fourth-quarter lead in their  loss to North Melbourne on Friday.
A poor 1-3 start to the season - ahead of a huge game against the Crows on Thursday night - comes after Carlton backed Voss last August to fulfil the final year of his contract in 2026.
Blues football boss Chris Davies on Saturday insisted he understands supporters' frustration, but said he could guarantee the club will resist any calls to sack Voss in the coming days.
"Yeah, I can, I absolutely can," Davies said on 3AW radio.
"We are 1-3 and if we are taking any positives from those three losses, it's that we have been in positions to win those games.
"But we are bitterly disappointed that we have been unable to get the job done, certainly in the last couple of weeks."
Davies, lured from Port Adelaide over the off-season, said his role was to support Voss, and defended 2018 West Coast premiership coach Adam Simpson's position at Carlton as a part-time leadership mentor.
"Adam's history in the game, his experience has been invaluable to Michael, and these are the times when you want to provide absolute support to your senior coach," Davies said.
"Having a person who has seen the ups and downs of a coaching career, I know that Michael is enjoying the mentoring and feedback he is getting from Adam."
Voss, in his fifth season at Carlton, acknowledged after the 14.12 (96) to 13.8 (86) loss to North Melbourne that pressure would continue to build.
He found an ally in retired former Blues captain Sam Docherty, who urged the club to hold the line with the 50-year-old mentor.
"It would be a really poor decision (to sack Voss now)," Docherty said on 3AW radio.
"They didn't back him in fully and give him an extension, but they backed him in to see out this year of footy.
"After changing most of the assistant coaches and a new GM of footy, a bunch of list changes, we're four games into a season and I think it would be a really hasty call to do that.
"I think you've got to let it ride out and see what happens over the next little period and then make the decisions."
Docherty, who called time on his 184-game career last year, spent a dozen seasons at Carlton and was on the list when senior coaches Mick Malthouse, Brendon Bolton and David Teague were sacked.
He said the Malthouse experience - the coaching legend was sacked eight games into the 2015 season - should serve as a warning about axing a coach so early in the year.
"The sugar hit of a caretaker coach has a life-span, but I remember by about round 14 or 15 ... that year was absolutely hell," Docherty said.
Carlton defender Nic Newman said Voss remains an "incredible leader" for the club.
"He fronts up like good leaders do," Newman said on 3AW.
"He was pretty calm and measured about the (North Melbourne) game and felt we played some good footy in the third (quarter).
"There were just some moments late, and it wasn't the same issues as last week, but it was more around some moments that we didn't own. We'll go to work on that."
The Blues will be without vice-captain Jacob Weitering against Adelaide after the key defender was concussed against North Melbourne.
Will Hayward is also set to miss after being offered a one-match ban for striking Kangaroos young gun George Wardlaw.
Hayward hit Wardlaw late with a swinging arm to the midriff as he kicked North into attack.
