How do I have a Mediatek USB driver for Linux to flash a smart phone?

I am a Linux beginner, I just wanted to know how I properly download and use a "**Mediatek USB driver**". I am using a Linux Mint MATE, and I cannot turn on the USB debugging of that phone because it was locked via FRP. When I open it and go to the settings, I cannot activate the Developer options. I wanted to fix (or flash) phones for free, but I can't because I am not able to download the MTK USB driver, which is needed to help my PC communicate with the phone. It seems that all MTK USB drivers are perfectly fine for Windows, that's what I saw on the internet and tutorials on YouTube. The phone I currently reviving is; **Vivo y69** with a **MT6750** chipset which suffers from **FRP lock**. I have 2 working properly with "SP flash tools" with different versions, an official auth file, a scatter file, and a DA file. I just need an MTK USB driver. Every time I attempt to flash the phone, nothing happens. It doesn't show any lights it doesn't boot up and the progress bar on my PC does not show any changes. I hope you can help me because I have already searched the web and downloaded different files but nothing has worked so far. I'm desperate to fix the phone(s) to give them new value.
