It's benign. From my perspective the two file systems are not unsupported (at least from a windows perspective). The windows system partition is 'DOS FAT' (I don't use EFI), although having said that, the windows defrag application I use which will only Trim an SSD partition doesn't provide the functionality to trim the system partition, it only provides functionality to trim Drive C. The Drive C partition is 'NTFS'. I think the main issue with the failure, assuming that where systemctl is indicating that the trim process is being done via fstab specified mount points, that it actually is, the two windows partitions mount points are 'Read Only' because of Microsoft functionality, in which case write processes are not permitted.
