You can use backports if you want a newer kernel, e.g. trixie-backports has 7.2.11.
That, or just pick the kernel package from unstable or testing. Apt is smart enough that mixing packages from different versions of Debian works just fine.
(I mean nothing is 100% but I've been mixing packages for like 2 decades now and literally can't remember any specific trouble resulting from it.)
