Not if they are Tuya-made devices: Tuya has not let released any “matter over Wi-Fi“ wireless switches that I know of, although they may in the future.
But regardless of brand, if they are indeed individually certified for “matter over Wi-Fi“ then they should work with SmartThings with the usual requirements.
FAQ: What do I need to add a Matter device to the SmartThings app? Do I need a bridge router device?
All of this is off-topic for this thread, though, so I’m going to move it to a new thread about wireless switches.
