TL DR: There is no content for removing unused kernel modules which is something some users would need. Maybe if someone answers it here, you can copy it to the wiki? I am staying away from wikis since I hate edit wars and all the drama in the discussion section.
The debian wiki has only an empty section about this topic. https://wiki.debian.org/ReduceDebian#Remove_unnecessary_kernel_modules https://superuser.com/questions/1490811/how-to-remove-unused-kernel-modules
