Ethics committee meetings - Online or face to face?

Ethics committee meetings are held periodically, with all members being physically present in the meeting room. During the COVID-19 pandemic, and the lockdown, a number of committees have resorted to the use of videoconferencing. Online meetings have significant advantages over physical or face-to-face meetings, though the guidelines and regulations imply that online meetings should not be the norm. Considering the advantages of online meetings in terms of saving time and costs, can the regulations and guidelines be tweaked to allow them even after the lockdown is over?
