nozzle upgrade ender 3v3 se

I've been printing PLA for a year since I bought ender 3v3 se. Now I've bought PETG filaments from numakers and based on my research, I need to use better nozzle.

Could you guys suggest a hardened nozzle for ender 3v3 se i could buy within India? I came to know that ender3v3 nozzle is a bit different from older ender models.
