Site Sharing - Specific People

Since M365 Business Basic does not support sharing with Anyone I have decided to do a tweaking but the question is can it support a Wiki page to be accessed by only to person in the company?

Below is the sample Wiki page supposed to be exclusive to two people only 

Without using this option since we have not yet used the exchange server the email wont be receiving yet by the user informing of the site for their exclusive access.

Or is this way even possible?
