Roll back to Root on Huawei Honor View 10

I have Huawei Honor View 10 phone I got it bootloader unlocked and rooted with magisk while bootloader unlock option was available on Huawei website. After sometime I upgraded to Android 10 update (EMUI) from Huawei which caused me to lose root. If I rollback to previous version... 1. Do I get bootloader unlocked as earlier 2. Will it be rooted or require me to root it again looking to hear from someone who has been there done that.
