Include ignored column in EFCore - entity-framework

Question

I have a scenario where I'd wish to ignore a column (so that it get's not joined on every include etc.) but include it explicit if I need to. Selecting all the other columns needed on every join is not a practible solution for me. I store a user's profile picture in the DB and the owner, midifier etc. gets joined on almost every object, making some queries pretty slow.
Is there a best practice for this scenario?
Edit: I thought about creating a 2nd, virtual Model mapped to the same table containing only this one column but two models mapped to the same table seam to make some problems.

As you have added in you Edit section. That is how I solved a similar problem.
This works for me and it runs in production today.
And I can easy include the the Body filed when I need to.
public class Content
{
public Guid Id { get; set; }
public string Heading { get; set; }
public string Preamble { get; set; }
public virtual ContentBody Body { get; set; }
}
public class ContentBody
{
public string Body { get; set; }
public Guid Id { get; set; }
}
This is where I do the Model mapping:
public class ContentMap : IEntityTypeConfiguration<Content>
{
public void Configure(EntityTypeBuilder<Content> builder)
{
// Primary Key
builder.ToTable("Content");
builder.HasKey(e => e.Id);
builder.Property(e => e.Id).ValueGeneratedOnAdd();
builder.Property(p => p.Heading).HasColumnName("Heading");
builder.Property(p => p.Preamble).HasColumnName("Preamble");
// Relationships
builder.HasOne(t => t.Body)
.WithOne().HasForeignKey<ContentBody>(t => t.Id);
}
}
public class ContentBodyMap : IEntityTypeConfiguration<ContentBody>
{
public void Configure(EntityTypeBuilder<ContentBody> builder)
{
// Primary Key
builder.ToTable("Content");
builder.HasKey(e => e.Id);
builder.Property(p => p.Body).HasColumnName("Body");
}
}
