NRF9160 set pin to high without VDD-GPIO

Hi,

is there any way to get a Pin to a defined "high" without vdd-gpio ref?

In our situation the NRF9160 Power is a Battery with 4,1V and the VDD-GPIO is 3,3V with a regulator. Now we want to be able to shut down the regulator (with a logic high to regulator circuit) for a secound but of course if we shut it down also the VDD-GPIO voltagedrops and the pin for shut down is not high anymore. this ends up in a loop and it can never reach a low enough voltage of the regulator.

Is there a internal reference or any trick we could use to "save" the state of vdd-gpio for the pin, even if vdd-gpio gets disconnected? 

best regards

daniel
