Can bidders be blocked from submitting RFIs/questions after X number of days of the bid being opened?

Content (please ensure you mask any confidential information):

For supplier negotiations, the client would like to know if bidders can be blocked from submitting RFIs/questions after 15 days of the bid being opened.

Based on my research, the answer is no, but the "Prebid Submission" option can be used to help answer questions up front and streamline the negotiation process.

I would like to confirm this prior to giving a definitive answer.
