This work like this? i need to reboot for change modes? (sorry dumb question...)

Im trying to put my raspberry pi to just read mode, but im executing a python file that sometimes (in a scenario) need to save somechange to a file.
I can put in my python file a sentence to execute your program and from there change between read mode and write mode without reboot? or i need to reboot to change between that modes?
Thanks!

This is something I would like to know too.
After seeing #4 I would assume all I need is use raspi-config to disable the overlay and it should instantly be writable but looking at overctl I can't see it working without a reboot.
Maybe we could have a chroot option?
