You can't use the DVI output from MMBasic at all. It isn't supported. You can use its pins for other things if they are available on the GPIO port though.
The on-board SD card is hard-wired to GP18, GP19, GP20 and GP21.
The PicoMite VGA system, used with normal Pico boards, uses resistors connected to GP18, GP19, GP20 and GP21 to produce the RGB video signals for the VGA port. GP16 and GP17 produce the sync signals. None of these pins can be changed.
Consequently, you could add the external resistors and connections to GP16 - GP21 and connect them to a VGA socket then connect to a VGA monitor, but you couldn't use the on-board SD card then.
If you wanted an SD card as well as VGA then one could be added *externally* to different GPIO pins.
