Vegeta always did physical training, I think that's part of the reason he was always BEHIND GokuVegeta got a trick up his sleave don't fret
Whis told goku he might of should of had been training with his rival vegeta, once vegeta got out the chamber
When about to run that fade with hit he told goku don't waste your energy, as if hit would have worked goku, implying he maybe stronger and look at goku as a Lil nikka
He ate a mafuba unfazed and didn't come out like he got the ass whooping of his life like frost or the immortal zamasu
He didn't get upset when goku transformed, just what was that, we'll talk about this later.... As if he has reached the form briefly but didn't understand the transformation...but may give it a shot and see goku synopsis later in the tourney
My guess is Vegeta has the form, and he'll master it without the heat drawback of goku's, now that he analyzed its flaws
But remember when Whis told vegeta that if he focused on his Ki he could surpass Goku..
Fast Forward, Goku got Ultra Instinct.
But let's not skip over the fact Vegeta did this TOO vs Ribrianne when she did the roll move
Plus if we go back to him training, he would always be steaming when he would come back from training but peep the LAST time he came out of the Hyerbolic Time Chamber
His body was in a relaxed cool state (As Whis told him to focus on his Ki)
He's always trained out of selfishness and wanting to be better than Goku out of ego
But now with his family on the line and him being a family man (Vegeta has had massive character development) shyt different for son now
His fighting spirt should be a lot more like Goku who always fought for others
Even when Goku reached UI, Vegeta was more curious than shook.
Like he had already achieved that state, or at least knew he could reach it as well.
I'm 90% sure Vegeta got a transformation up his sleeve
We'll see tho..
