If you search cisco.com for "A9K-RSP440 RAM upgrade" you'll get a page
that, basically, says "remove the passive -TR, put int the first -SE,
wait for it to sync up, then failover redundancy, then swap the other
one".  So it should be straightforward and supported.

Haven't done it, never take my word on it, find the page yourself :-)
