Is it possible to disable wireguard on specific Wi-Fi ?

an example:
my laptop e.g. has

Address = 172.22.247.58/32
PrivateKey = xxx

[Peer]
PublicKey = xxx
AllowedIPs = 172.22.144.1/32, 192.168.0.0/23
Endpoint =  myhomeIP:51820
PersistentKeepalive = 25

172.22.144.1/32 is the wireguard-IP of my wireguard-server at home.

This way I can reach for example my printer at 192.168.0.10 even if I am 
on the move, because my wireguard server is installed on my router at 
home (Unifi USG-3P).
The printer sends it packets for 172.22.247.58 simply to its default 
gateway, which is my router/wg-server, that forwards it over wireguard.

When I'm in my network at home, my laptop gets the IP 192.168.1.72/24 
and automatically talks to the other devices in the LAN without taking 
the wireguard route, because the subnet is more specific.
