I believe this is already handled in the library.

The request info class looks to handle the types already here https://github.com/microsoft/kiota-dotnet/blob/ae93dbc61908d8048a92cecf13564be2782685d0/src/abstractions/RequestInformation.cs#L127

Furthermore, validation checks are passing as the tests below are part of the suite.
