Wireguard Windows client/exe - disable creation of routes

[Tim]

Hello,

Does anybody know how one can use the Wireguard Windows
client/executables to establish a connection but not have the
client/executables modify the Windows routing tables.  Functionality
similar to the "Table = off" in the linux WG but using the Wireguard
Windows executables (wg.exe/wireguard.exe)?

My goal is to use the existing executables but to handle route
creation on my own.

I've tried "Table = off" but it does not work.  Nor does a cursory
examination of the source code.  Though this seems to be something
basic, so I imagine I am missing how to do it.

Any idea?

Thanks
