Is there any settings that could possibly speed up encoding of simple videos?

I'm making long "videos", it is just a simple edit.

It has a long audio .wav file about 40min~1h, a static .png image, subtitle from time to time that appears, a simple spectrum from After Effect and Cross dissolve in both, image and spectrum.

The only thing needed is to be in 1080p for the background image to be in high quality and an FPS rate enough for the spectrum not look too slow.

Settings I'm using now for video is 1080p, 29.97fps, Format mp4 (H.264). VBR 1pass and 10mbps.
For audio AAC, 48000hz, Stereo and 320kbps.

Since I have an Nvidia GPU, I chose H.264, which could speed things up a bit since nvidia has a chip to hardware-accelerate h.264 encoding, but it seems that's not the case because the GPU barely hits 50%, or my GPU is just not compatible with it.

My PC specs are a RTX 2060 6gb, Ryzen 5 5600 (stock clocks), 32gb 3600mhz RAM.

The PP and AA cache are on a HDD and saving the encoded file on a SSD NVME with a read/write of 7,000/6,000MB/s

PP and AA versions are 25.1.0

Unfortunately I think all the H.264 acceleration happens on the CPU, not the GPU. I'm not as familiar with PCs but I know that Ryzens lack the Quicksync that Intel chips enjoy.

Does sending the clips to Media Encoder help?
