I haven't had to compile a linux kernel for probably 15 years, but I always used an epoch so that my kernel-image package could have the correct version number but would always be viewed as newer by the APT programs. It was just a matter of adding 5: between the underscore and the upstream version. (5 is a random choice, you could choose 202003051130: if you wanted to timestamp it.) Cheers, David.
