Can I use more than 1 kali to connect to the exam env for eWPT?

Like the title, as some tools only can be installed on vmware kali vm, but I usually use the virtual box kali vm, can I install same VPN file on the two kali for the eWPT exam? Hope I can get the answer as soon as possible since I plan to take the exam soon in one week.
Thank you very much!
