Workaround for multiple monitors on M3 iMac

I am in the process of buying a new iMac for my office. I currently use a 2019 intel Macbook Pro and have two 4K monitors hooked up to it. I was hoping to get a blue iMac (512GB SSD, 16GB RAM, 8 Core CPU and 10 Core GPU) and hook up my current 4K monitors to that. However I discovered the M3 chip is limited and can only have 1 external display for a total of 2 monitors.

Would I be able to buy a displaylink adaptor as a workaround so I can have two 4K external monitors plus the screen of the iMac as a 3rd screen? I have found this one so far which has great reviews: https://www.amazon.com/dp/B0CS8D3KF2?ref_=cm_sw_r_ud_dp_MK6NEE7GF3SMCG1NFYY0. Maybe there is one Apple sells that would be compatible?

The reason I do not want to get a Mac Mini or Mac Studio is because I need a webcam, microphone, and speakers and I would rather have something that is all-in-one.
