using 2017 iMac as external display for pc laptop

I would like to use my personal iMac (Retina 4K, 21.5-inch, 2017, running Catalina OS) as an external display for my new office-issued Dell pc laptop. Both the iMac and the laptop have Thunderbolt ports; is there a way to do this?

iMac 21.5″ 4K, macOS 10.15

You can connect ONLY any of these older iMac models to another Mac from 2019 or earlier for use as an external display. Learn how to identify your iMac model.

Target display mode requires macOS High Sierra or earlier on the iMac used as the external display. It does not work with macOS Mojave or later.
