I'm working on GTP and I need to recompile the kernel for every release to activate the GTP in kernel
I need to do

Is it possible to enable it by default ?
I used it since 6 months without issue.

Start with Microsoft/config-wsl and inspect the existing CONFIG_GTP setting alongside the surrounding network options. Enable CONFIG_GTP by default there, then verify that the resulting WSL kernel configuration includes it and that the kernel build completes successfully.
