AL4002A for Ambika

Hello! I have recently started sourcing parts of a Ambika build. I’ve been having trouble sourcing a proper HD44780 compatible 40x2 OLED screen. I bought a AL4002A (not cheap!) from midiphy, without checking to see if it was 5v or 3.3v :expressionless: It’s rated for 3.3v. Is there any way to modify this part in the Ambika build? I am comfortable with SMD rework

I just noticed there is a 3v/5v jumper here. I wonder if that is all there is to it? Wish I could find more information like a schematic online.
