Not to my knowledge. There may be an adapter available, but I have not seen one and some sort of adapter would be necessary since the mac mini uses the 12+16 pin Apple form factor for the SSD.
Also the 6+12 Pin drives use SATA rather than PCIe so I am unconvinced they would be easily adapted regardless. In my opinion, you would be better off putting in a 2.5” SSD rather then trying to install the 6+12 pin.
