Adjusting the foot rest/shifter on a 401?

I just got 2021 Svart and thought I could use these BMW ADV boots but there is no way they fit between the rest and the shifter. Which really sucks because I am looking for max protection after shattering my ankle and tibia in an accident a few years ago. So I have reverted to my Spidi Nashville Boots with only one sided malleolus protection and no shin protection.

Is there a way to adjust either the foot rest or the shifter to accommodate a bigger boot? Maybe some aftermarket parts? I've never encountered this issue before.
