Is it possible to seal up a dirt wall?

Hello, I am currently renting a house with a partially finished basement that we are trying to turn into an office space. On the far end, there is a half wall that is about 3 feet of dirt and rocks, topped by the concrete foundation. I actually like the look of the wall, very rustic and stone like, but if you accidentally touch it, it spews dust and rock crumbs everywhere. Is there anyway to give this wall a coating? To seal in the loose dirt and dust? Obviously since this is a rental, we are looking for affordable solutions--we even considered covering it with protective sheet of plexiglass, but the cost was too high. Would Drylok Siloxane would on this kind of wall? Or perhaps spraying linseed oil? Any advice would be most welcome! Thank you!

I wouldn't use linseed oil as it's prone to mildew. Thompson's Water Seal might fit the bill but you really ought to run it by the landlord first.

if it's dusty and crumbly I doubt anything will stick to it. The best solution to preserve the look is to build a framed wall with plexi inserts spaced about one inch away from surface. Yes it will be expensive. You might be able to use the heat shrink mylar streched over the frame that is used to insulate windows during winter time.
