How to ignore a Navigation property ( not using Fluent API ) - entity-framework

Question

How can I ignore a navigation property without using FluentAPI in the onModelCreating for the below example:
Table Layout:
My Classes are below. When I use my contact to get results for PmActionDetail, the WorkTask table includes the AssetTypeWorkTask results, which is not the desired result.
public partial class PmActionDetail
{
public int PmActionDetlId { get; set; }
public int? AssetTypeWorkTaskId { get; set; }
public virtual AssetTypeWorkTask AssetTypeWorkTask { get; set; }
}
public partial class AssetTypeWorkTask
{
public AssetTypeWorkTask()
{
AssetPmTypeWorkTask = new HashSet<AssetPmTypeWorkTask>();
}
public int Id { get; set; }
public int? AssetTypeId { get; set; }
public int WorkTaskId { get; set; }
public virtual AssetType AssetType { get; set; }
public virtual AssetWorkTask WorkTask { get; set; }
public virtual ICollection<AssetPmTypeWorkTask> AssetPmTypeWorkTask { get; set; }
public virtual ICollection<PmActionDetail> PmActionDetail { get; set; }
}
public partial class AssetType
{
public AssetType()
{
AssetTypeWorkTask = new HashSet<AssetTypeWorkTask>();
}
public int AssetTypeId { get; set; }
public string AssetTypeDescription { get; set; }
public virtual ICollection<AssetTypeWorkTask> AssetTypeWorkTask { get; set; }
}
public partial class AssetWorkTask
{
public int Id { get; set; }
public string Desc { get; set; }
public virtual ICollection<AssetTypeWorkTask> AssetTypeWorkTask { get; set; }
}
Here is the context query I am running:
return await _context.PmActionDetail.Include("AssetTypeWorkTask").Include("AssetTypeWorkTask.WorkTask")
.Include("AssetTypeWorkTask.AssetType").ToListAsync();
These are the results. I do not want to show the relationship for assetTypeWorkTask under "workTask". I understand why it is perhaps showing it, since it is part of the relationship. However, its not the result I need.
