You can open a bug against zram-config package:

https://packages.ubuntu.com/focal/zram-config -> bug reports

And suggest that change in a patch.

Perhaps, instead of hard coding the comp_algorithm, having a debconf
option to a high priority would be more appropriate, as you can always
default to one specific algorithm.
