flag for setting useragentdata

[Sarthak42]

Is there any flag available, like the one for changing the useragent from the command line, to change the user agent data that contains brands, platform etc information.

In other words, i want to change the user agent and the meta data(example given below) by using chrome launcher.

Example: "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36", "platform": "Win32", "userAgentMetadata": { "brands": [ { "brand": "Chromium", "version": "121" }, { "brand": "Google Chrome", "version": "121" }, { "brand": ";Not A Brand", "version": "96" } ], "fullVersion": "121.0.0.0", "platform": "Windows", "platformVersion": "15.0.0", "architecture": "x86", "model": "", "mobile": false }
