SharePoint Missing Authentication for _vti_bin

The issue with the vti_bin folder is that it is accessible without authentication. However, the remediation measures outlined below are not technically feasible for SharePoint Online (O365). I found few remediations for this issue which are as follows:

Configuration Options:

Administrators can configure authentication for _vti_bin through various methods, such as:

• Enabling anonymous access:This allows anyone to access the site and its resources, including _vti_bin URLs, without logging in. 
• Restricting access in Web.config:The Web.config file can be modified to deny access to anonymous users for specific _vti_bin paths. 
• Using the ViewFormPagesLockDown feature:This feature can help restrict access to certain SharePoint resources, including those within _vti_bin

I would like to verify whether the provided fixes are applicable to O365 SharePoint. If they are not, could you please advise on alternative solutions that can be implemented to mitigate this issue?
