a while ago i've submitted a ticket (13966) about this option in the modeler for grids, it's scheduled for backlog.
Maybo not the most desirable solution, but if you want to do this in every datagrid, you could position the pagination somewhere else with css:
.mendixDataGrid_pagingStatus {
margin-top:100px;
}
Doing this with styling has many disadvantages, but if you really want this and have the right css skills, you could do it.
