Force DbContext to throw Exception on SaveChanges() in unit test

I´m using EF Core 2.2.0 with an InMemoryDatabase for testing. Is there a way to make it throw an exception when an operation is called, such as SaveChanges or Find?

I want to verify that a my business logic is handling the exception in a particular way. I know that I can abstract the DbContext all together, but with EF Core and the InMemoryDatabase I wish to access the DbContext directly without any more abstractions.

In my unit test I'm currently creating the DbContext as such:

var dbOptions = new DbContextOptionsBuilder<MyContext>()
        .UseInMemoryDatabase(Guid.NewGuid().ToString())
        .Options;
var context = new MyContext(dbOptions));

And my logic (extremely simplified):

public MyClass
{
    private MyContext _context;

    public MyClass(MyContext context)
    {
        _context = context;
    }

    public void SomeMethod()
    {

        try
        {
            */ .. Other stuff .. */
            var entity = context.Find(id);
            entity.SomeProperty = "Foo";
            context.SaveChanges();
        }
        catch(Exception e)
        {
            // I want to test this code...
            Log.Write("Something");
            DoSomethingElse();
        }
    }
}
