Welcome to the Community Forums.
Checking MTM 81DE0048IN goes with PN 5B20R19899 (MB L 81DE I58250U RADEON530_2G D4G NOK). The board description do not indicate that it is intended for optane.
Comparing this with the motherboards provided with 81DE models on the parts lookup page like MTM 81DE021HIN (with optane 00UP481), PN 5B20R19869 (MB L 81DE I58250U UMA D4G OP WIN). OP would imply the optane ready boards so we can not guarantee that Optane technology would be supported.
I hope this helps answer your query.
