Limiting the file size of .qcow2 files

Qcow 2 files are an open source file format for virtual machines. In my opinion, unlike .vmdk files, they do not offer the option of specifying a maximum file size. This means that they can constantly grow in size for various reasons. What ways are there to limit the growth of the file size of .qcow2 files when used under Debian 12 derivatives such as LMDE6 to a certain value or to be able to achieve a fixed file size? Perhaps they are better ideas, than to use a own partition for every .qcow file. One alternate idea can be possible, to use a file system for storing the .qcow file, which offer to set a quota by folder or by file for the file system, which are used to store the .qcow files. But that's are only ideas on this moment.
