Can we display more number of projects on the help center page

In the latest versions of Jira service management, the help center page displays projects as tiles ( Earlier it used to be hyperlink) and currently it can display only the 6 projects. We have a requirement to show more number of projects, as the users might find it hard to select the projects. I’d raised a support ticket as well but they are asking to check in developer community.

Anyone who had done these changes, please help on where and what changes should be made to the source code.
