Is there any way to rebind Push To Talk?

I use a colemak keyboard layout, and my movement keys are FRST instead of the usual WASD, or even ESDF. This was never an issue until the game came out on Steam and my friends started playing. Now every time I strafe to the right everyone can hear me twice because we use discord.

I can’t find the option to rebind PTT anywhere in game or even in any config files. So do I seriously need to switch keyboards and muscle memory just to play with friends?
