Yes.
The Toe Switch is a fixed assignment but the Expression pedal, of set to wah will automatically control whichever slot the Wah effect type has been loaded into. However, I don’t think you would necessarily need to disable the TS as long as you don't have another FX in the slot you normally use for Wah when using Wah in Slot X you should be fine. In fact, even if you do have another FX in the normal slot (say Stomp A for example) as long as you don’t push the TS when using the Wah you should still be fine. The Wah bypass is an Effect level setting so you should be able to just change it from On to Bypass at ....... in the specific rigs where it is in slot X.
If you want to have the ability to bypass the Wah with a footswitch click you can assign one of the I - IIII buttons on the remote to do this for specific rigs rather than use bypass at.... if you prefer.
I haven’t actually tried this so I am not 100z sure it will work but I’m reasonably confident so give it a try.
