Can these chargers be modded?

Bought this from Aliexpress under the impression that it would be some Kingpan style charger. It MAY be, but it looks completely different in the inside. For sure some resistors are responsible for current and voltage adjustment, and I may find out which one to change.

I need CURRENT adjusted. Voltage is fine.

Anyone did any mod on this type? Any experience? Any ideas?

Thanks!

I'd start looking for a thin trace going from the current shunts. You may have to flip the pcb around.
The resistor to be changed is most likely on that small daughterboard sticking up.
