Tweak your 1G1R ROM set to your liking - andrebrait/1g1r-romset-generator GitHub Wiki

Sometimes, you can have some very specific set of requirements.

The good news is that this is exactly why I created this tool in the first place. To see the full set of options, refer to the Usage section of the README.
