I want to disable my NVMe SSD and only turn it on when I actually need it. Whenever the PC starts, the drive receives power even when I am not using it, and I'm worried that this will shorten its lifespan after recently having another SSD fail unexpectedly. Physically removing the drive is inconvenient because I also have to remove the GPU. Is there a reliable way to cut power to the NVMe while it remains installed, or is it normally powered whenever the computer is on?

You could put the SSD in a USB NVMe enclosure and connect it only when needed. Some enclosures or adapters have a power switch, but this is generally less convenient and may expose the drive to more handling or connection-related risks. Also, simply being powered on is not normally what causes meaningful SSD wear.
The more important solution is having a good backup strategy. SSDs can fail for reasons unrelated to how heavily they were used, so keeping another copy of anything important is much more useful than cutting power whenever the drive is idle.
An NVMe drive doesn’t significantly wear out just because it has power. Most endurance wear comes from writing data, not sitting powered on while idle. If the drive isn’t being actively used, its wear should be negligible.
A BIOS option might let you disable or hide an M.2 device, but that usually won’t physically disconnect its power. Motherboard-level power switching for individual NVMe slots is uncommon, so there probably isn’t a built-in way to do exactly what you want.
