I would like to understand if it is possible to load a GML file in GeoServer and serve it over WFS.
Thank you in advance

It is not possible to load a GML file into GeoServer. GML is a transport format not a storage format as while it compresses easily it has no indexing and as a text format is very hard to search efficiently.
You can use ogr2ogr
to convert your GML into an number of formats that GeoServer can serve as WFS layers. The most efficient would be to store the data in a well indexed PostGIS database.
