Sharing ethernet only on Wi-Fi 6E

Question

I have an Intel AX210 card Wi-Fi 6E card to share Ethernet over Wi-Fi 6E connection only, using the hotspot function.

I typed nm-connection-editor, clicked Wi-Fi -> Hotspot and there is no choice for 6E band.

I am only allowed to choose between A (5GHz) or B/G (2.4 GHz).

I really need to force it to 6E because the hotspot connection is supposed to be the backbone with another 6E computer. Thanks.

This is a print out from sudo lshw -class network

In short, if your location does not allow 6E, the AX210 won't operate in that frequency.
