It’s not technically possible given the bandwidth available on a TB3/TB4 port. 5K display requires 22Gbps, the port overall is limited to 40Gbps, so not possible to get more than one on a single cable. Due to the way TB uses the available lanes in the cable, it’s also not possible to my knowledge to support a USB-C 4K monitor daisy chained off a 5K monitor either even though there’s sufficient bandwidth (22 + 15 < 40) to do so.

Thunderbolt 5 w/ it’s supposed 80Gbps support will change that.
