Here are the relevant excerpts from Nystul's Magic Aura spell:
You place an illusion on an object you touch so that divination spells reveal false information about it. The target may be an object that is not worn or by another creature. […]
False Aura. You change how the target appears for magic spells and effects, such as detect the magic, which detects magical auras. You can make sure that a non-magic item appears magical, a seemingly unnoticeable magical object, or change the magical aura of the object so that it seems to belong to a school of specific magic of your choice. When you use this effect on an object, you can make false magic obvious to any creature that manipulates that object.
And the Glyph of Warding spell:
When you cast this spell, you register a glyph that harms other creatures, either on a surface (such as a table or floorboard or wall) or inside a closable object. (book, roll, etc.). a treasure chest) to hide the glyph. The glyph can cover an area not exceeding 10 feet in diameter. If the surface or object is moved more than 10 feet from where you cast that spell, the glyph is broken and the spell ends without being fired.
The glyph is almost invisible and requires intelligence verification (inquiry) with your DC spell save.
Can you use Nystul's magic aura spell on a glyph of protection to hide it completely from detection or at least give it the impression of being something else?
