allow apps to install to SD card

My phone is limited in internal space (unfortunately, the original ROM is totally bloated and leaves little space). Thus, I prefer to install most apps to my SD card. Apps have to have a bit flipped in their metadata to be installable to the SD card. Find more information at https://developer.android.com/guide/topics/data/install-location. I'm not sure how to set this in the f-droid metadata or else I would have provided a patch. I did inspect the metadata for some apps but did not spot the relevant flag. I'd appreciate a pointer.

Some of the apps that currently cannot be moved to SD

some big apps that are currently installed to internal memory by default
