One Plus 8T disable / override Idle mode

[gotnone]

I want to leave a One Plus 8T plugged in, but the only charging switch that is available gets stuck in an Idle mode. If the current charge voltage gets above the voltage limit if I use a acc -s v=3900mv or the pause capacity if I try acc 45 the phone can not discharge down to the desired voltage. I have set allow_idle_above_pcap=false and have tried prioritize_batt_idle_mode=no, but the phone refuses to discharge when connected to a charger.

Does anyone have experience with the 8T? I looked to see if the oem-custom.sh had any tips, but the charging switches for the OnePlus contained therein do not exist on the One Plus 8T running LineageOS.
