Multiple dvc.yaml files

Hello, is it possible to track 2 or more projects in one git/dvc repo? For example having 2 separate folders for 2 different neural net models. Like that:
DVC_repo/PyTorch_model and DVC_repo/TensorFlow_model where DVC_repo is the root directory. Is it possible to have 2 dvc.files in each folder and run them one at a time but without needing to dvc destroy when switching between them
