Validation of file column type

[Emilian_Bem]

Is it possible to validate the file type column in such a way that, for example, the upload of pdf files is prohibited?

Others may be able to suggest a direct way to do that. Meanwhile, to accomplish your goal, consider Use data from Google Drive to create a table of files within the app and using an automation to detect undesired file types. There might also be helpful ways to leverage Apps Script.
