The following types need to the normalized to their RFC3339 representation before they are passed to std URI template when they are present are query or path parameter values
DateTime, DateTimeOffset, and their collection representations (array, enumerable)

I believe this is already handled in the library.

The request info class looks to handle the types already here

kiota-dotnet/src/abstractions/RequestInformation.cs

Line 127 in ae93dbc

DateTimeOffset dateTimeOffset => dateTimeOffset.ToString("o"),// Default to ISO 8601 for datetimeoffsets in the url.

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