I did a little googling and, unfortunately, resistors without an active handshake can only ask to increase the current limit of the charger. Qualcomm QC looks a bit simpler than USB-PD and can call to increase the voltage, but requires some handshaking, probably nothing a tiny micro can't help you with

many LED driver chips accept an analog voltage on the dimming input. some are dual-mode and accept either analog or PWM, or even both at the same time
