Multi-Process Service setting CUDA_MPS_ACTIVE_THREAD_PERCENTAGE variable while application is running

It seems that setting the CUDA_MPS_ACTIVE_THREAD_PERCENTAGE variable while the application is running does not immediately change the active thread percentage, it only takes effect after the application is restarted. Is there any way to apply the change of allocated SMs to an application while it is running? For example, when I have multiple Tensorflow applications sharing an A100 GPU using MPS, when I change the CUDA_MPS_ACTIVE_THREAD_PERCENTAGE variable, I have to restart all the applications, which brings in extra overhead.
