How to root Huawei p20 lite without a computer?

Hi folks I have a Huawei p20 lite and want to root but it doesn't work with King root then I wanted to try it differently but I don't know how to root differently but without a PC so how can you root without a computer on the huawei p20 lite

Unfortunately not possible. Nowadays you have to unlock the boot loader before root, and as far as I know, this can only be done with a PC via fastboot. The root itself goes on the cell phone.

To be able to root, the boot loader must be unlocked beforehand, and Huawei no longer allows this.

That means you won't get the device unlocked for free.
