The full-back was dropped during the Test series defeat to South Africa in June and was overlooked by Eddie Jones for the November internationals.
Harlequins stalwart Brown is determined to add to his 72 caps and will discover on Thursday whether he has been selected by Jones.
"Obviously I'm massively disappointed not to be involved, because I'm desperate to play for England." the 33-year-old, speaking on behalf of Land Rover at an off-road driving event, told Omnisport.
"That desperation and commitment never changes, whether you have played loads of times, whether you're in, you're out.
"It's always been the same for me, that goal of playing for England and how much I want to do that. All the hard work that I try and do to achieve that doesn't change and that's no different at the moment.
"I'm out of the team, I just want to get to get back into the squad and put myself in the best possible situation and place for selection."
