Checking for the existence of a gzip file and setting up htaccess?

Question

htaccess

Tell me how to configure the return of gzip files through .htaccess, if it exists?
Those. do not reap the server, but check for the presence of a gzip file, and if it exists, then give it away (without the .gz extension, but with the title that it is a compressed file), if there is no gzip file, then give the uncompressed version of the file, for example, there is 3 files:

style.css
style.css.gz
style.ie.css

...
<link rel="stylesheet" href="css/style.css"/>
<link rel="stylesheet" href="css/style.ie.css"/>
...

style.css is given compressed (the .gz extension is removed from style.css.gz, respectively), and style.ie.css is given as is.
Is it possible to do this via .htaccess?
update: Accordingly, this is necessary for different types of files, in particular, for *.js, *.html, *.css

You don't need to upload files in .gz format, everything works on the fly.
