Sure, you could write one yourself (configurable policy is what SELinux
is all about amongst other things). Theres also this:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/security/SELinux.txt?id=e22619a29fcdb513b7bc020e84225bb3b5914259

But it has a bug that only recently got fixed

No matter what you choose, it is going to be a little hard if you arent
confident with SELinux

For the real adventurous theres my base policy, which needs tweaking to
get it to work:
