I have a PicoMiteVGA and have the setting OPTION SYSTEM I2C GP0,GP1 but I noticed that I cannot start it without the RTC. Is there a way of disabling OPTION SYSTEM I2C without having to reprogram the Pico?

This is what the manual states:
OPTION SYSTEM I2C sdapin,
sclpin
? Specify the I
2C port and pins for use by system devices (eg, RTC).
The PicoMite VGA uses a specific I
2C port for system devices,
leaving the other for the programmer. This command specifies which
pins are to be used, and hence which of the I
2C ports is to be used.
The pins allocated to the SYSTEM I2C will not be available for other
MMBasic SETPIN settings but can be used for additional I
2C devices
using the standard I2C command. Note: I2C(2) OPEN and I2C(2)
CLOSE are not available in this case
