You can chain two maps to get a logical and:

map $request_method $is_get {
default 0;
GET 1;
}

map $http_cache_bypass $bypass_cache {
default $is_get;
"" 0;
}

proxy_cache_methods POST;
proxy_cache_bypass $bypass_cache;

# note the lack of : after default in the maps, it's incorrect to have it
there like your original map did
