How to prevent internal MOSFET from being precgharged?
If you don't mind adding a little control logic for the start-up sequence, you could do something like this:


With no voltage applied to the gate of the P-channel JFET, it is a relatively low resistance. Once your circuit has biased, pull the JFET gate high to make it a high resistance. The value of the resistor to the MOSFET (if any) I will leave to you.

I use this technique to guarantee output states during start-up in some places (where the state of signal matters at all times, but during start-up we cannot know the actual state of the signal).

This is one possible solution.
