Huawei Mate 10 Pro Bootloader Codes?

I have a Huawei Mate 10 Pro and want to flash it with Lineauge Os. My problem I do not have a bootloader code and I'm desperately looking for an inofficial solution, but everything I tried so far did not work. Does anyone have a solution for me that works 100%?

No, Huawei does not give out unlock codes anymore

Yes I know, and I do not want to buy on reputable websites. Are there any programs where are very unknown but effective

I mean there must be some possibility, otherwise I'm desperate

No, that's not possible, you need to access their server for it
