Yes, you can use a motherboard without a VRM heatsink.

I also wanted to hear about the temperature you noticed a YouTuber using an i5 10th gen processor with this motherboard. He mentioned the VRM reached around 100°C and also warned that it might shorten the motherboard's lifespan. In your setup, you only had one intake and one exhaust fan.
I won't rely on a stock cooler and will disable turbo in the BIOS, meaning VRM temperatures become relevant only during overclocking.
It concerns the power consumption of the CPU. The i3-10100 draws 65W, and it won’t be subjected to high demands that would exceed that level for an extended period since it can’t be overclocked. A fixed CPU with a 65W power rating won’t strain any contemporary VRM. The 10900K comes with a 125W power output from the start. After significant overclocking, that figure rises considerably. Absolutely, it will cause a poor VRM to fail. Yes, definitely.
