How to set PPMd method when compress to zip from command line

[mdadm]

I want to create zip archive with PPMd compression method from command line because I noticed it has best ratio when compressing plain text files, but I get error about wrong argument (or something like that):

System ERROR:
E_INVALIDARG

I try that commands:
7z a -tzip -m=ppmd file.7z file
7z a -tzip -m0=ppmd file.7z file
7z a -tzip -m1=ppmd file.7z file
...
7z a -tzip -m9=ppmd file.7z file

but when changed archive type it worked:
7z a -t7z -m9=ppmd file.7z file
7z a -t7z -m9=ppmd file.zip file
7z a -t7z -m9=ppmd file.xz file

Is PPMd in zip format not supported from command line 7z? I remember that I could do that from 7-zip file manager.

I use last version of p7zip (16.02) in linux.

By the way: is any difference between:
7z a -t7z -m0=ppmd file.7z file
and
7z a -t7z -m9=ppmd file.7z file
?

So my question is: how to set PPMd method (or any other then default deflate) when compress to zip from command line?
