Welcome to our HP community forum!
No, the Ryzen 7 5800X3D is not compatible with OMEN by HP 40L Gaming Desktop GT21-0xxx platforms.
These high-end processors are compatible with your PC:
Ryzen 7 5800X (3.80 GHz up to 4.70 GHz, 8-Cores, 16-Threads, 105-watt TDP)
Ryzen 9 5900X (3.70 GHz up to 4.80 GHz, 12-Cores, 24-Threads, 105-watt TDP)

Who do I believe?
Well, I am the kind of person who believes in facts on the ground. So, I believe in over 1,800 HP System OMEN by HP 40L Gaming Desktop GT21-0xxx Users where none have installed a Ryzen 7 5800X3D: UserBenchmark: HP OMEN by HP 40L Gaming Desktop GT21-0xxx Compatible Components.
Point being, I would think it exceedingly unlikely that if a Ryzen 7 5800X3D was compatible with your system, not to see a single User with it...

It is a pre-assembled PC, so they do not usually do component upgrades. I have contacted HP support and they have told me that the processors in the 5000 range are compatible since the motherboard has an AM4 socket.

Well, then, since HP is adamant a Ryzen 7 5800X3D is compatible with your system, go with it.
If they are correct, please follow up!
