The boards are going to need whatever power it requires. Get one official PSU for each and use a power strip to plug them into if you have access to just one outlet.
The official psu is cheap and of high quality and will just work with the pi.
"My pi is not working" or "I get low voltage warnings on my pi" is probably the number 1 issue people come here asking for help and 99% of the time the PSU they used is no where near adequate to run a pi, never mind a power hungry cluster of them.
Your other option is something like this: https://www.amazon.com/gp/product/B06XK ... =UTF8&th=1
but that one is overkill for 2 pis. They have smaller ones that will work. You just power the pi via the GPIO pins. But by the time you buy one of those, get the correct wires, etc, it'll be probably cheaper to get 2 separate official PSUs and later you can use each pi independently from each other for something else when you're done with the cluster.
