How to set up Referer in Headers?

[AkulovArtem]

Hi, I'm trying to set up Referer in Headers, but I'm not getting anywhere. I tried this code, doesn't work, through Options and cdp_cmd, still Referer is empty:

options.add_argument(f"--referer={reffer}")

driver.execute_cdp_cmd('Network.setExtraHTTPHeaders', { 'headers': { 'Referer': 'https://example.com' } })

How to customize this? Or is customizing custom Referer in Headers not available in uc?
