The things I was reading acknowledged that the M2 could only support one monitor, but they presented the docking station as a workaround.
There are workarounds that add second-class display outputs – but no workarounds which add, or can add, first-class hardware-supported ones.
Examples of such would be the DisplayLink dual-HDMI adapters from OWC and SonnetTech, and the DisplayLink dual-DisplayPort adapters from SonnetTech. These involve having third-party software set up virtual displays on your computer. The software periodically sends out compressed updates (using the vendor's proprietary format) to a "magic decoder" chip set in the adapter/hub/dock. The chip set unpacks the video into a more regular form, to drive HDMI or DisplayPort monitors. (Note: despite the similarity in names, DisplayLink is a different thing from DisplayPort.)
There may be artifacts and lags if you try to use these adapters for fast-changing high-resolution content. (Even the vendors may tell you that these adapters are not the best solution for playing high-end games.)
If Apple releases an update to macOS that breaks the third-party software, you'll be dependent on the vendor (or their technology partner) to update that software.
If you try to play DRMed video from commercial streaming services, you might also run into an issue where DRM throws a hissy fit and refuses to let you play video as long as the extra monitors are attached.
