Has it been any update or progress in this line? I recently encountered a similar problem that I posted in [Nested and different AD methods altogether: How to add AD calculations inside my loss function when using neural differential equations?](https://discourse.julialang.org/t/nested-and-different-ad-methods-altogether-how-to-add-ad-calculations-inside-my-loss-function-when-using-neural-differential-equations/108985) that I am trying to make work. Thanks!
