Looks like most changes here and below use tabs instead of 4 spaces. See 
[0] for more information on the indentation for our JavaScript projects.

Also relevant here: I think it'd be better to add all three SEV types to 
`sevEnabled` here, so we do not need to modify any `!sevEnabled` to 
`!sevEnabled && !snpEnabled` below.
The `snpEnabled` can stay as it is here, as it's relevant for the pflash 
warning and the "Allow SMT" checkbox ofc.

The "Allow Key-Sharing" option should be disabled AFAICS for SEV-SNP 
being set, no?
