Komento with onesignal adds manifest.json

Komento uses and adds manifest.json

<link rel="manifest" href="/manifest.json">

I already declare and use site.manifest which is the new web standard.

<link rel="manifest" href="/site.manifest">

I appreciate that onesignal is still using manifest.json see this github post but I need to turn this off as it will mess up other services such as my favicons.

I need this to be removed or an ability for me to turn it off.

NB: I dont think easy blogs adds this header.

Komento v3.0.11

thanks
