With windows 10 lifetime coming to an end, even though the Enterprise edition still going to be supported for some while, eventually the world will move on to Windows 11.
Unless someone breaks that cycle of Windows being the dominant OS.
Are you sure your computer really doesn't have TPM? Because Intel CPUs since Haswell and AMD CPUs since Zen 1 have firmware-level TPM (implemented at the Intel ME / AMD PSP side) built in, but disabled by default, but you can mostly turn it on in BIOS/UEFI setup interface (if the BIOS supports it), and Windows 11 will work with it. And sometimes even discrete TPMs on motherboards come disabled by default.
If you haven't already, check your BIOS for TPM/fTPM settings (or if you're on Intel also look for "Intel Platform Trust Technology" or "Intel PTT").
