Bootloader on Ender 3

Hi All and Thanks for accepting me in this Community.
I’d like to install Marlin 2.0 on my Ender 3 but i need a bootloader, is it possible to upload it with Platformio? If yes, anyone can help me?
Thanks to all,

I have the same question, have you get it sovled?

I bought Arduino 1 and solved using this and not with PlatformIo
