Sounds so interesting: the NVMe SSD should provide Health % of course.
If there is no Health %, then there may be wrong/old driver installed which does not allow detection of complete status. It is very common under Windows 7 or 8.1 as described at:
or if you have an older AMD BOTTOM RAID driver installed.
If you use Report menu -> Send test report to developer option, I can check and assist about how to get complete status of this NVMe SSD too.
If you prefer to hide the tray icon of any disk drive, then please open Configuration -> Hard Disk Drives page (where you selected the single tray icon with highest temperature but DO NOT select that) as there you can toggle which drive(s) should have tray icon displayed by DOUBLE CLICK on the drive.
If you prefer to hide any disk drive from the main window, just right click on the list of drives in the upper left area and un-check it.
