Same as with Debian but with a different repository:

https://www.devuan.org/os/packages ← see the "Add backports" section.

EDIT: the advice in that section is wrong though because the backports repository should be left enabled to ensure the backported packages are kept updated; this is particularly critical for the kernel metapackage.[1]

The backports repository's InRelease file has these lines:

NotAutomatic: yes
[snip]
ButAutomaticUpgrades: yes

^ Those confer a pin value of 100 and ensures that packages can only be installed explicitly (eg, apt install -t chimaera-backports) but also that they will be kept updated from backports once installed.

[1] I've also had this argument with the MX Linux developers. I am right.
