The 2015 17 R2 is not on the Alienware Laptop Windows 11 tested/validated list. This means that we are not going to create a new BIOS or drivers to address issues encountered trying to use Windows 11.
Well that's lame. There's zero reason why these devices can't run Windows 11. Poor support all around. Even a Macbook would be getting an update 7 years later.
Keep in mind that this is not a Dell decision. MS has stated that any CPU pre-gen 8 will not be supported. Which means all manufacturers are in the same boat with older processors. Can you run Windows 11, probably. I have a Latitude E5430 running Windows 11 just fine. And I have TPM 1.2. But as @DELL-Chris M has stated, Dell will not be offering support for a system that does not meet MS requirements. So should you require Dell tech support, they will insist you install Windows 10 before offering any assistance. Now Windows 10, a stable and very good OS, support ends in 2025 and due to the age of your system you will probably be upgrading by then to a new system. But if you want to run Windows 11 do a YouTube search as there are many videos on installing Windows 11 on non-supported systems.
As far as TPM is concerned, have you looked at the BIOS for a setting named PTT? It should be enabled. This web page may help.

It seems to be a secure boot option where if you disable it it should allow you to configure tpm.
