How do I add my own patch to the build system?

[Tryanks]

My device is OrangePi5Plus, and I have built a custom kernel for it, creating a patch for the modifications I made to the kernel: https://gist.github.com/Tryanks/54cb0100a43d6362ac76df09665f1054.
I want to apply this patch to the build scripts in this repository, not to the kernel itself in the kernel repository, as it disrupts the cleanliness of the build process.
Have any suggestions on how to do this? I simply moved the patch file to the repository's patch folder, but it doesn't seem to have any effect. Also, I didn't see any related options in the configuration for the corresponding device.
