A Windows 11 24H2 ISO will install on a machine w/o a TPM 2.0 module using the command line argument "/Product Server". (You can do this as either an "upgrade" to Windows 10 or on a clean machine by using the Shift-F10 shortcut to get a command prompt and run the setup from there.)
I'm on mobile and don't have a reference handy but search-engine this and you'll find instructions.
