The answer is a categorical no. Even back in the days that a ‘war role’ was touted for Hawks it was the Hawk T1W which was capable of launching a sidewinder. The Red Arrows Hawks are not weapons capable in any way.
Aside from these points, if the UK were to reach a point where arming Hawk T1s were considered necessary (I’m not talking historically, I’m talking about contemporary Britain) then the country is already lost and you may as well just ask the Reds to give a display to the new occupying army as a way to welcome them.
