Hey all,
I've just designed a small daughterboard with a step-up/step-down regulator that might fix the issue.

KiCad project + some rough ideas on assembly can be found at https://github.com/TobleMiner/pinebook-p...-regulator
PCBs from JLC will take some time to arrive though. So there will probably not be any results until in a few weeks.
