@itikhono, could you please add MO Code Review template and fill?

I had a network with DeformableConv and when DeformableConv-8 was turned on I had performance degradation since CPU was using evaluate for inference. Looks like because of some attribute v8 was not successfully downgraded in IE. And even cherry-picking the current PR does not solve the problem. Moreover error occurs on nG side during validation.

@itikhono could you please check your changes on the model in ticket 59003 ?
