Pixel 6 pro profile not available for dng version 1.4

Google pixel 6 dng changed from version 1.4 to 1.6 on Dec 2022.  

LR will allow you to select the Pixel 6 profile on version 1.6 but not on version 1.4

Same camera phone....So is there anyway to get LR to allow Pixel 6 Pro profile on this earlier dng version.

...Or can I convert the dng files from version 1.4 to 1.6

...Thanks
