Edge function headers

Hi,

Does anyone know wether i can safely set

    headers.set('Strict-Transport-Security', 'max-age=31536000; includeSubDomains; preload');

    headers.set('Strict-Transport-Security', 'max-age=31536000; includeSubDomains; preload');

in edge functions? Or is this not allowed or might it brake some this?
