Lol at the downvotes, it’s like 3 clicks. Not rocket science.

Mint deliberately uses an LTS kernel because it’s primary value proposition is stability & simplicity but changing kernels is pretty safe.
<shrug> I’ve put later kernels on Mint a half dozen times withno dramas, but whether you should depends on what your use case, preferences and skill are.
I personally wouldn’t do the arse-ache that is an immutable system, but plenty here love their Bazzite it seems. Different strokes for different folks. Nothing wrong with that.
If you love Mint except for the kernel version then it’s an easy fix. If you don’t have deep feelings then either try & be ready to ditch, or pick an alternative.
Just for the record there is no “doing all that” about it. It’s a simple couple of clicks. It couldnt be easier. I’m not sure where you got the idea it was difficult.
