Could I “plug and play” a POST card?

I have just one PCI POST card and a number of PC. I want to inspect booting process of each, in a manner, that if one is successfully booted (code 00 or code FF typically) - i need to eject POST card, plug it to next and boot it.
But i had an issue, where a GPU on mining burned out, when accidentely was partitially ejected from PCIe slot onder load, so i am kind of.. afraid and studied now.
So my question is - can i safely eject pci (and pci-e) post cards from running system?
And in a bonus addition, if you managed to know - can i plug in a card on a running system? Will that work, or current code just will not be detected?

Is it PCI or PCI-e? They're electrically very different.

@grawity my case is precisely PCI and hot-ejection possibility. But to roll a great and more informative answer you are welcome add information about PCIe cards, and hot-plug possibility as well. It's a total of 4 combinations of PCI/PCIe and plug/eject - and what could happen in each case?

Even if it is theoretically OK in a particular case, I wouldn't do it. It's too easy to accidentally short things.

In principle, both PCIe and PCI can do hotplug/hot-ejection.
Whether this works on a concrete system is a totally different question - the controller must support it, the connector must support it, and often the card needs to be specially designed with a few shorter traces on the connector.
So: unless you know for sure that all components of your system are specifically designed for hotplug/hot-eject, doing it is not safe. It might work a few times, and create a short circuit or funny electrical situation the next time, and kill some components on card or motherboard you still need.

Possibly worth noting that it's much more likely for any arbitrary combination of PCI-e card and host system to work correctly with hotplug than conventional PCI, given that PCI-e has had hotplug as part of the spec essentially since the beginning and therefore has a standard API/ABI/electronics for it, while conventional PCI got it retrofitted by multiple independent companies, resulting in at least 3-4 different API/ABI/electronics options for it.
