vSphere Features Not Supported with Fault Tolerance.
Snapshots. Snapshots must be removed or committed before Fault Tolerance can be enabled on a virtual machine.
VM Component Protection (VMCP). If your cluster has VMCP enabled, overrides are created for fault tolerant virtual machines that turn this feature off.

Interestingly that, as per the “Mastering VMware vSphere 6.7” book by Nick Marshall, p.418, “Although you can use vMotion with SMT-FT protected VM, you cannot use Storage vMotion. By extension, this means that SMT-FT protected VMs cannot take advantage of Storage DRS.”
Even regular DRS has limited applicability for FT enabled VMs: “Unlike FT, SMP-FT’s utilization of DRS is limited to providing initial placement of VMs. This means that when SMP-FT is enabled on DRS clsuter, VM Overrides will be configured to disable DRS on protected VM”.
So, although the documentation does not list SDRS among unsupported features, in reality it cannot be used.
