Hello there! Your setup looks solid with an MSI MORTAR Max B450, 16GB RAM, and a R5 3400G. You're looking to enable your onboard graphics, which is great! I found some helpful YouTube guides for this. Just check those out and let me know if you need more tips! 
Consider linking the screen output directly to your motherboard's display port rather than relying on a dedicated graphics card. Remove the GPU unit and power cycle the system. Installing the correct drivers should allow you to utilize the built-in graphics capabilities.
You can obtain the manual from the MSI website by visiting your motherboard model's page at the provided link. Click on "Manual" and download it in your preferred language. The steps involve navigating to BIOS settings, choosing integrated graphics over PCIe cards if available, or leaving both enabled. Connect your monitor to the video outputs on the motherboard's IO shield and initiate the PC setup. Refer to page 46 in the English PDF for further guidance: https://download.msi.com/archive/mnu_exe...89v1.1.pdf. For IGD mode, set it to start with integrated graphics as the primary option, and dedicated graphics as a secondary one. To force integrated graphics even with a connected dedicated card, enable Integrated Graphics.
It could help with certain tasks that benefit from parallel processing, such as running simulations or processing large datasets. The iGPU might be suitable for light workloads like image enhancement or basic machine learning models.
