You cannot load dependent objects for more than 1000 resources. Use a filter to restrict your query.

Hi, I have on-premise SharePoint 2019 and MS Sql Server 2019. 
I use CSOM to set actual work for resources.

public TimePhase getResourceTimePhaseAssignments(EnterpriseResource resource, DateTime startDate, DateTime finishDate)
{
TimePhase currentTimePhase = resource.Assignments.GetTimePhase(startDate, finishDate);
projContext.Load(currentTimePhase.Assignments);
projContext.ExecuteQuery();
return currentTimePhase;
}

Running this code I get exception: Too many resources: 1073. You cannot load dependent objects for more than 1000 resources. Use a filter to restrict your query.

I found several unanswered threads related to this issue:

I didn't find any decision for my case. 

Is there an ability to change limit of 1000 resources somewhere on the server side?

Am I able to filter my request somehow?

Any help would be appreciated.
