If you do not want to crop the placed PDF page and you still want to get rid of the crop marks you have to open the PDF in Acrobat Pro and remove the crop marks there.
Two options when you switch to category Print Production:
[ 1 ] Edit Object, select the crop marks and delete them with the command in the context menu.
[ 2 ] Preflight, select Acrobat Pro DC 2015 Profiles and run the following single fix on the document:
Page contents > Remove printer marks and other objects outside BleedBox

On an InDesign file? On a PDF file? Usually, cropmarks are automatically created when the file is exported to PDF and do not exist in the InDesign file.
