Nbconvert Commandline Parameters usage in URL?

Is it possible to give nbconvert parameters via URL?
I have a JupyterLAB installed via docker on Localhost exposed at Port 888 and tried the following:
As well as variations like ...?PDFExporter.exclude_input=True&..., ...?c.PDFExporter.exclude_input=True&... an so on.
The result is always the same, PDF is generated with input fields, but I want them to be hidden. Result should be executed notebook just showing output of cells.
