Integrated GPU being used instead of dedicated GPU regardless of settings

My applications won't properly use my dedicated graphics card. This has been an ongoing issue for a while, but I don't recall for how long.

There's a similar thread of someone that has had the same issue but it didn't resolve anything for me.

My computer specs are here in a text file.

The example game I'll be mostly using is Grounded, since that's where I first noticed this. I've tried most solutions from other people on the internet, but none have worked so far. For some reason, only Discord seems to use my dedicated graphics card, which makes me think that the problem is in the software, not the hardware. I've got a screenshot of Discord using GPU 1 (my NVDIA card), whilst Grounded uses GPU 0 (my integrated graphics card). All other applications have been using GPU 0.

Strangely enough, while some games are opening, they say "GPU 1 - Copy" before switching to GPU 0 when booted. I'm not sure if this bears any relevance.

Things I've tried:

• Changing my Windows preferred GPU. This screenshot shows the preference for Grounded, while this one shows that the high performance processor is my NVIDIA card.
• Disabling my integrated GPU driver through device manager. Instead of using my dedicated GPU, programs will now run off the CPU instead. Attached is a screenshot of my Intel card being disabled. I dont have a screenshot of the apps in task manager using the CPU, but none of them were using my NVIDIA card after I disabled the Intel one.
• Changing the settings in the NVIDIA control panel. Although the control panel says the settings are now controlled by Windows, I made sure for them to prioritise the GPU usage anyway. Screenshot attached.
• Do a fresh install of both my graphics drivers. I did a clean install of the NVDIA drivers through GeForce Experience, and a clean install of the Intel drivers using Intel Driver and Support Assistant. Both are up to date and fresh installs.
• Enable hardware acceleration. This didn't make a difference.
• Alter my power plan and battery settings to always maximise performance.
• Enable performance mode on my computer through Control Center 3.0 (a driver package that I installed from my manufacturer, Metabox)

If anyone could please help me try to fix this issue that would be greatly appreciated. This has been bugging me for a while as it massively impacts game performance when games won't use my dedicated graphics card.
