Translate simple settings to advanced

[A Simple Man]

Yo!

After hours of researching YouTube for the best recording settings, I found this video: https://www.youtube.com/watch?v=wIrz4Vaaf8E
However, I want to be able to use advanced output mode so I can have multiple audio tracks.

Here are my settings from the log with the settings from the video:

10:51:48.172: [jim-nvenc: 'simple_h264_recording'] settings:
10:51:48.172: rate_control: CQP
10:51:48.172: bitrate: 0
10:51:48.172: cqp: 16
10:51:48.172: keyint: 250
10:51:48.172: preset: hq
10:51:48.172: profile: high
10:51:48.172: width: 1920

10:51:48.183: ---------------------------------
10:51:48.183: [FFmpeg aac encoder: 'simple_aac_recording'] bitrate: 192, channels: 2, channel_layout: 3

Above settings was achieved from this:
Recording Quality: Indistinguishable Quality, Large File Size
Recording Format: mp4
Encoder: Hardware (NVENC)
Downscale Filter: Bicubic (Sharpened scaling, 16 samples)
Fractional FPS Value: 240/1
Process Priority: Above normal

Can someone explain how I should setup this in advanced mode please?
What encoder is this?

Here are my PC specs:
MOBO: ASUS PRIME Z370-A
CPU: i7 8700K
GPU: ASUS GeForce GTX 1080 Ti 11GB STRIX

If you have any tips on optimal settings for me or any tips for upgrade I would love to hear that!
