BedrockMultisiteValetDriver.php

        return !! preg_match("/define\(\s*('|\")MULTISITE\\1\s*,\s*true\s*\)/mi", $app);
    }
}

if youve changed

Config::define('MULTISITE', true);

to

Config::define('MULTISITE', env('MULTISITE') ?: false);

to be able to control this via envs you need

     // .env has MULTISITE='True'
        $envFile = file_get_contents($sitePath . '/.env');
        $envFileHasMultisite = preg_match("/\bMULTISITE\s*=\s*['\"]?true['\"]?\b/i", $envFile);
