elfprince Not without changes to the build tooling or sideloading the package AFAIK
It wouldn't make a difference anyway. The problem is not that it gets bigger through the package compression (in fact it still manages to squeeze out some compression), but simply that the uncompressed files get compressed so much better. See here for a comparison of the two archives, the one on the left just before the switch to compressing the files before they get added to the package, the other one after:
You can see that the uncompressed size of the packaged files is clearly much smaller in the second case (almost half), but the compressed size is quite a bit bigger. Disabling package compression would make it slightly bigger yet.
(Note also that eopkg itself uses a different compression algorithm to compress whole packages than the zstd one used on the files in linux-firmware itself during the package build, and it can compress the whole thing as one, accounting, among other factors, for the difference in total compression ratio)
Disregard the huge file number increase, those are just symlinks due to an unrelated usr-merge change.
