Multi-GPU system. Use x GPU for display output, y GPU for hardware acceleration?

Hi. I'm about to install LibreELEC for the first time, but I have a question first.

I have a system with 3 GPUs because of reasons. The display output is on a Radeon R7 240 which is unable to do HEVC acceleration.

But I also have an Intel iGPU which has the ability to decode every codec I need.

Is it possible to have the Radeon GPU's display output active while using the Intel iGPU's hardware acceleration in Kodi?

Thank you!
