Daisy chain two external monitors with mac mini m4

Hello community,

I've just purchased a mac mini m4 which can support up to 3 external monitors.

I have a Lenovo ThinkVision P27h-10 monitor which do not have thunderbolt capability.

I am thinking of buying one Thunderbolt 4 monitor to form the mac -> thunderbolt 4 monitor -> ThinkVision P27h-10 set up through thunderbolt daisy chaining.

Upon researching I find there are different types of thunderbolt 4 monitors.

1. Monitor with both thunderbolt 4 upstream and thunderbolt 4 downstream ports. (Dell u2724DE, HP 727PU, Samsung Viewfinity S80TB)
2. Monitor with only one thunderbolt 4 upstream but no thunderbolt 4 downstream port. (HP 732PK)

Need to confirm below point for buying the right monitor.

Assume the mac mini m4 will connect to the first monitor's thunderbolt 4 upstream with a genuine thunderbolt cable. Is the thunderbolt 4 downstream port required on the first monitor to achieve daisy chain to the second one? If the first monitor has no thunderbolt 4 downstream port, will the daisy chain work if I connect first monitor's display port output to the second monitor's display port input?

Thanks in advance.
