The £24 million striker has been stripped of the captaincy and then dropped from the first team since Lambert took over from Alex McLeish this summer.
However, the England international insists he is happy at Villa Park, will fight for his place in the team and won't ask for a transfer.
"If they feel in January it’s time for a parting of the ways then that’ll be down to them — it won’t be my doing," Bent told The Sun.
“It won’t come from my side. I won’t ask for a transfer, of course I wouldn’t do that.

“Villa are a massive club and I always want to play for huge clubs.
“For me to ask for a move would be silly, especially at this stage of the season when there’s still a long way to go.
“Everyone would like an explanation about why things happen, but that’s not the manager’s style and I respect that.
“I’m not going to go in and say I want to leave.
“I’m more than happy at Villa and to play my football here. The attraction is the size of the club, the history and a massive fan base. I’m prepared to give it as long as it takes.”
Losing the captaincy was a bitter blow for Bent, who took over the armband from Stilian Petrov. The 28-year-old former Charlton, Tottenham and Sunderland striker says he was shocked to have to give it up.
He added: "It’s the manager's decision — he appointed me captain and then took it away.
“That’s down to him but it’s frustrating for me.
“At first I was shocked to get the captaincy — but I was delighted with it.
“Then I was shocked to lose it."
