Windows 11 and T1700 - upgrade path, is it possible?

Hi Everyone

i have a client who has 5 T1700 Precision workstation

All fail (as expected) the MS Windows health check with TPM and CPU revision

OK so the TPM is probably disabled in BIOS and I know the Xeon is too low a rev for win 11 so i was wondering has anyone found a cost effective upgrade path fro these old workhorses

Heres the stuff from sysinfo 

Device Encryption Support       

Reasons for failed automatic device encryption: TPM is not usable, PCR7 binding is not supported, Hardware Security Test Interface failed and the device is not Modern Standby, Un-allowed DMA-capable bus/device(s) detected, WinRE is not configured, TPM is not usable

Processor          Intel(R) Xeon(R) CPU E3-1270 v3 @ 3.50GHz, 3501 Mhz, 4 Core(s), 8 Logical Processor(s)

any help /advice much appreciated
