Webdav limit file size

greetings to all

I would like to know if there are any parameters in the webdav, to limit the weight of the files in upload, I would like to set it for 1 GB per file.
via browser I edited the file php.ini

I await your answers / explanations / tutorials anything to make me understand how I can change these parameters

Thank you very much!
