CubeCell AB02 OLED power off for deep sleep

I have a HTCC-AB02 and without the OLED initialized, the deep sleep current with my connected MHZ19 sensor (via P-MOSFET at Pin14) is below 10 µA. But when the OLED display is initialized with display.init(), the deep sleep current after setting Vext=HIGH is always 10 mA. How can I switch off the OLED display completely for deep sleep?

i’ve tried to figure out a similar case without measuring current and disconnect the screen before go to sleep mode seems to work : display.stop() … and at wake up display.connect() where display is a SH1107Wire object.
