Connecting to Wi-Fi LAN from Android without disabling WireGuard. But isn't there any better way?

Problem

Last week, I bought a new Pixel 9a. While setting up, I realized I couldn’t connect to the Wi-Fi LAN with Wireguard Interface on.

After cursorily searching, I found it’s almost impossible to modify the Android routing policy from a normal user unlike GNU/Linux.

But It’s a bit cumbersome to turn on/off every time I want to connect to the LAN, so I took a different approach.

I aimed only IPv4 LAN network and used the normal WireGuard app, and some other apps (e.g., Proton and Mullvad) may behave differently.
