I was able to carry out a search and unfortunately we do not have the USB4 variant in our range and it is currently not possible to procure it as none of our suppliers have a corresponding purchase offer. If and when we will be able to offer it is unfortunately not known at the moment. Alternatively, there are the following models with a Thunderbolt 4 / USB 4 port, but not with AMD but already built-in Intel CPUs:
ASUS RNUC14RVHI300002I, Intel Core 3 100U
ASUS NUC 14 Pro RNUC14RVKI300002I, Intel Core i3
ASUS NUC 14 Pro Slim Kit RNUC14RVKU500002I; Intel Core Ultra 5 125H

I was able to do another search and we already offer this product:
AsRock DeskMini X600 USB4

Thank you for your reply.
