I'm surprised you're not using HIP? At least in my experience it seems like HIP is the go-to system for programming the AMD GPUs, in large part because of CUDA compatibility. You can mostly get things to work with a one-line header change [1].

(I work for a DOE lab but views are my own, etc.)

[1] As an example, see the approach in: https://github.com/flatironinstitute/cufinufft/pull/116

HIP is just the programming language/runtime, ROCm is the whole software stack/platform.
