i succeded flashing gsi rom, it's working great.
don't flash magisk in twrp or patch boot.img with magisk because booting gsi rom failed, only with the stock boot.img that's working.

edit: i can use supersuser PHH but is there a way to make magisk working on gsi ? i wish to pass safetynet attestation

    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    Code:
     * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or your getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    Supported Models:
    Galaxy S21 G9910, G991U, G991U1 and G991W.
