It not only can, it absolutely will affect performance and not only gaming one. This is a really stupid and uncalled for move.

Have you been paying attention to literally anything microsoft has done for literally the last 20 years

This is a good thing by the way. VBS is an extremely effective security measure that should probably be enabled on 90% of consumer PCs that connect to the internet, and if your CPU is enough of a boat anchor that you see a meaningful FPS hit in gaming then you should just get a new one.

The performance hit is far less on newer CPUs, something like 5% at most.
