Hello,
I noticed that currently I cannot disable 'allow-smt' in the WebUI.
The default value for allow-smt in qemu-server is '1'.
So setting it to 1 or no value in the WebUI results in allow-smt always being
enabled.
To fix this, you can explicitly set allow-smt to 0 when the checkbox is not
checked.
Also, currently if I uncheck the allow-smt checkbox, save it to config and then
reopen the window, the 'Allow SMT' checkbox is checked again.
See my suggested fixes inline:

Expand input panel with AMD SEV-SNP selection, and relevant optional
parameters similar to existing options for AMD SEV(-ES).
Further, upon selecting AMD SEV-SNP, issue a warning that EFI disks are
not included when using SEV-SNP.
