there might be an BIOS update you could try i don’t think it will fix 64 bit and even if it did 32bit apps probably take less memory for storing addresses on my AOD255E 64bit just works :tm:

apps like https://play.google.com/store/apps/details?id=com.parseus.codecinfo (https://apt.izzysoft.de/fdroid/index/apk/com.parseus.codecinfo) show whether or not you’ve got it, on my samsung galaxy note 20 ultra I’ve got software only :(
