GPIOZero can use several different pin factories. The suggestion is that you use lgpio:
https://gpiozero.readthedocs.io/en/late ... pins.lgpio
When the doc says "if no default factory can be constructed (e.g. because no GPIO implementations are installed, or all of them fail to load for whatever reason)" and "on a Raspberry Pi with the RPi.GPIO library installed, (assuming no environment variables are set), the default pin factory will be RPiGPIOFactory", I suspect you'll find that if "lgpio" is installed and RPi.GPIO isn't then "lgpio" will be the default. If not, you can change the default: https://gpiozero.readthedocs.io/en/late ... in-factory
In fact, you can see the order of preference in the code (https://github.com/gpiozero/gpiozero/bl ... es.py#L274):
