Two default gateways. One DHCP one Wireguard

looking for the best way to resolve this situation. They both have an AD of 1, I cannot change that as the lowest is 1 I can assign. I set a static route for my client so it will not go across the tunnel. What is the best way to route the rest of the traffic across the tunnel instead of the default assigned by DHCP? Having the same AD on both is making it so the traffic has no real default route and a lot of stuff is failing.

Not enough info
Network diagram gives context
Describing user requirements without any config speak is essential
identify users/devices groups of users/devices and their traffic flow requirements
Finally config of devices at both ends of tunnel
