No, commercial jets have a blunt nose for structural reasons and pilot visibility while landing. SR-71, F-16 and so on all have pointy noses.
Passenger airliners travel at slower speeds for which more round noses are actually better (eg to prevent flow detachment).
In fact, iirc I read somewhere that Airbus’s more blunt noses are the result of newer CFD-based design techniques whereas Boeing reuses their pointy nose from previous designs.
A round nose has a flat bit at the front which reflects radar direct back towards the enemy that you're flying towards. Military planes generally have no surfaces facing directly forwards for that reason - even surfaces made of plastics reflect some radar when they get wet.
