UWF overlay includes files on the exclusion list

Question

This question has technically been answered already 2 years ago, but I was hoping there might be an update meanwhile.

We have enabled the UWF (type RAM) on a Windows 10 IoT LTSC device, which will be used in an industrial environment. The device has pre-allocated ring buffers (total size around 2.5 GB), which are used to store data that is collected from various sensors. The folder containing the buffers are on the UWF exclusion list, but the data still ends up on the UWF overlay. Not the whole 2.5 GB luckily, but the overlay keeps filling up with every sensor reading being added to the buffer.

The same question has been answered in 2020 here: https://learn.microsoft.com/en-us/answers/questions/107695/uwf-overlay-contains-files-on-my-exclusion-list.html

My question now is: will there be an update to the UWF anytime soon? Windows 10 IoT should be suitable for embedded devices, but having the UWF overlay filling up with buffers that are configured to be excluded from the UWF gives me a big headache.
Am I correct that in case the problem is not and will not be fixed, my only options are (device restart is not an option):

1. Add more RAM and increase the overlay size
2. Switch the UWF overlay from RAM to DISK?

Or is it somehow possible to "clear" parts of the overlay?
