I wrote a set of uBo rules to do the same on TikTok. Not sure if they still work, but might as well publish it:
tiktok.com##sharing-main-video-el:watch-attr(controlslist):remove-attr(controlslist)
It seems a bit flakey on mobile, but it was a nice addition to the other enhancements. I haven't been able to make the mobile web as useful as the desktop web version, but didn't want to spend too much time on it either.
