Saved module/row


I have an event plugin which generates individual event posts, the posts are editable by beaver builder only their content areas, but not the entire page. So only modules and rows are applied the content area as well.
But the good thing is the plugin has template.php page which I can edit and insert some codes.
So I want to add saved rows as the header and footer of the posts which I already created.
So I am asking, is there any way to add the saved row? Such as simple coding as ;
get row (saved row id = 21321); or something like get module (saved module id = 21321); to add onto the template page? Or is there any quick way to achieve the goal? Appreciate your insight. Thanks in advance!

Thanks so much! It’s the exact solution I was looking for. Appreciate it!
