Use TF2 saved_model.pb with OpenCV dnn module

Recentryl I have trained mask_rcnn_inception_resnet_v2_1024x1024_coco17 with TF2 Object Detection API and exported the model in saved_model.pb. Than the challenge was to actually use this model with OpenCV dnn module which is practically impossible. Is there any support in this area? What can we do so we can get support for TF2 saved_model.pb ?
