Rooting Huawei Y7 2019

Hi, I'm trying to root a Huawei Y7 2019 DUB-LX1 but all methods I've tried have failed. Apparently, TWRP is not supported. I've tried one touch root apps like Kingroot and Kingoroot, both the apk and the pc version and all failed. I found another method requiring the boot.img from the firmware but after downloading the firmware I can't find the .img. What can I do? Is rooting possible in this device?
