DirectoryObjects.GetByIds and select in v5

Is your feature request related to a problem? Please describe.
The Graph API has a know issue with getByIds https://learn.microsoft.com/en-us/graph/known-issues#incomplete-objects-are-returned-when-using-getbyids-request
With the graph sdk v4 it was possible to use this:

                var dictionaryObjects = await graphServiceClient.DirectoryObjects
                    .GetByIds(chunk)
                    .Request()
                    .Select("id,type,displayName,mailNickname")
                    .PostAsync();

Describe the solution you'd like
A way to use the select parameter with the getByIds Post method in v5

Describe alternatives you've considered
Stay on v4

or

use the ToPostRequestInformation and overwrite the URI

                var ri = graphServiceClient.DirectoryObjects.GetByIds.ToPostRequestInformation(
                    new Microsoft.Graph.DirectoryObjects.GetByIds.GetByIdsPostRequestBody()
                    {
                        Ids = chunk.ToList(),
                    }
                );
                ri.URI = new Uri(ri.URI + "?$select=id,type,displayName,mailNickname");
                var dictionaryObjects =
                    await graphServiceClient.RequestAdapter.SendAsync<GetByIdsResponse>(
                        ri,
                        GetByIdsResponse.CreateFromDiscriminatorValue
                    );

Additional context
Add any other context or screenshots about the feature request here.

Start with the DirectoryObjects.GetByIds POST request and the ToPostRequestInformation and SendAsync usage shown in the issue. Determine how v5 request options represent the $select parameter, then verify that GetByIds can send the requested fields without URI overwriting; the issue provides no test file or implementation path.
