No. Currently, Apple M1-based MacBook systems (non-Intel processors) only support a single external display. This limitation is a result of computer itself, and not the device. Any Thunderbolt 3 dock or graphics adapter shares this same display restriction (Plugable-branded or otherwise).
For adding additional displays to M1 Macs, the single display restriction can be worked around through the use of a USB graphics solution such as DisplayLink. Please refer to DisplayLink-based docks such as our UD-3900PDZ for more display support.
