I am using the ROG Maximus Z790 Dark Hero. I would like to downgrade to NVM31 to use Thunderbolt 1 & 2. Could you please provide the downgrade tool?

Hello, I am on a TUF GAMING Z690-PLUS WIFI D4 and would also like to downgrade to NVM 31 for the same reason, please could you provide me the tool as well?

Many thanks.

Hello @kie65 

Thank you for reaching out to us.
According to the specifications of the TUF GAMING Z690-PLUS WIFI D4 motherboard, this model does not include a built-in Thunderbolt card. However, it does feature one Thunderbolt™ (USB4®) header for add-on card support.

May I confirm if you are currently using the ThunderboltEX 4 add-on card?

Thank you.

Hi @Jiaszzz_ASUS ,

I've recently installed the PRIME Z790-P mobo with the ThunderboltEX 4 card. May I please have the downgrade tools to NVM 31 so that I can use my focusrite Clarett 8PreX, which is Thunderbolt 2, with it?

Thank you!
