An instance of the web asset server serving more instances of specify 7

Is there the possibility of working with a single instance of the web asset server serving more instances of specify7, separating each database into different folders? I read the configuration file documentation but I couldn’t understand how to set the options WEB_ATTACHMENT_COLLECTION = None
SEPARATE_WEB_ATTACHMENT_FOLDERS = False

I went to the reported github topic but I also couldn’t understand how to do it. can you help me?
