I have latest Linux kernel and Ubuntu 20.04

Linux max-work 5.7.0-050700-generic #202006082127 SMP Mon Jun 8 21:30:38 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Have no Discrete GPU.

My CPU (for which I'm trying to setup 3rd monitor) is Intel(R) Core(TM) i5-7400, which does support 3 monitors as per intel official docs: https://ark.intel.com/content/www/us/en/ark/products/97147/intel-core-i5-7400-processor-6m-cache-up-to-3-50-ghz.html

I have 3 1920*1080 monitors, any 2 of them are working perfectly fine with each other. Connectors are DVI, VGA and HDMI.

When I connect 3rd monitor, one of them gets disconnected and when I try to manually enable it I have the following message in settings: Message screenshot. (Changes Cannot be Applies. This could be due to hardware limitations).

Of what limitations does Ubuntu says, as CPU is clearly supporting 3 monitors, and each of them individually are working fine?

You've indicated in comments that your motherboard uses the H110 chipset.

The Intel H110 chipset only supports two displays at a time using the integrated GPU.

You will not be able to connect three displays at a time with your current hardware.
