Applying patch file to ubuntu server

Can someone please explain how to apply a patch file to ubuntu server kernel? I'm trying to apply this patch file which enables the

option in the TCP communication options on an ubuntu server. I followed this answer and tried to apply the

.patch

but got the same error. Here are my steps: first, I changed the directory to the kernel source folder:

cd /usr/src/linux-headers-5.15.0-58-generic

Then I run the command

-p0 ~/file.patch

But I got the following info and it keeps asking me to enter the file to patch

can't find file to patch at input line 44
Perhaps you used the wrong -p or --strip option?

I think I am working in wrong directory but I am not sure.
