There are no BT2020 consumer monitors, so that is not an option.
If you do not have a calibrated monitor, pick disable calibration

This isn't correct.
There are no consumer monitor covering 100% of BT2020, but there are many consumer and monitors and projectors offering a BT2020 mode that covers above rec-709, often up to P3 and for some projectors like the RS4500/Z1 beyond P3.
So there is an advantage to selecting a BT2020 mode in the display/projector, even if the projector is unable to cover BT2020 fully. For example, with my rs2000 that covers close to 100% of P3 with its P3 filter, I benefit a lot from selecting the BT2020 calibration (around 100% of P3 with a P3 filter) or the HDR calibration (around 90% of P3 without filter). Both deliver a significantly larger color volume than the rec-709 calibration, for HDR/SDR WCG content of course.
With madVR, especially if you use 3D LUTs, it's usually better to select a DCI-P3 calibration as it tends to be closer to the actual capability of the display and madVR can simply discard the BT2020 container and deliver P3 which is used to grade the majority of current content, even if it's delivered within a BT2020 container. But with a consumer source you don't have the choice, they either output rec-709 or BT2020 so you have to select one or the other if you want to track the correct saturations.
