Rendering .qmd files on Posit Cloud

Hello.

I teach a course about data analysis, which has approximately 20 students. I have always used RStudio for this course and I would like students to use RStudio in Posit Cloud. I think the most convenient would be the plan in which the instructor pays and the students don't have to pay.

The problem I would have is that when rendering a .qmd file, a background job always stays activated, which would add a lot to the money I have to pay because students may not manually stop the background job.

I would like to know if there is a way to automatically disable this background job. Another option would be for students to only be able to generate .Rmd files, which are generated without keeping an always-on background job. In this case, I would like to know if it would be possible to disable the option to create .qmd files, to prevent students from mistakenly creating a .qmd file instead of a .Rmd file.

Best regards,

Armel
