The short answer is that it can't be done. C# doesn't support type functions. https://github.com/dotnet/csharplang/issues/339 is probably the issue to follow if you want to track their progress.
Workarounds are going to require another type parameter and probably a factory method: e.g.
public TEntityEntry_TEntity Add<TEntity, TEntityEntry_TEntity>(
[NotNull] TEntity entity,
[NotNull] Func<TEntity, TEntityEntry_TEntity> wrap)
where TEntity : class
where TEntityEntry_TEntity : TEntityEntry;
