Any way to add another Filter operator for SQL SoundEx?

Does anyone out there know if there any method to add SQL SoundEx() (I'd call it "Sounds Like") operators to the DataFilterxxx components?
Am using SQL exclusively and would like to have SoundEx capability in the standard filter operator dropdowns etc. As not everyone is using SQL it would seem this should be optional.

As I'm doing gRPC data retrieval, I'm already processing all the expressions myself, just need a new FilterOperator name/description to appear in dropdowns and a # returned in objects such as the CompositeFilterDescriptor.
Would prefer not to write my own filter display components. I'm not however seeing a lot of virtual methods I could override to support my effort and don't want to use a custom modified copy of Radzen.Blazor.

I'm afraid that this is the only way.
