Welcome to the forum!
You'll need a modded BIOS in order to utilize that card.

Thank you! Could you explain a little more detail? I'm planing to use new WiFi card with this router
Asus RT-AC68U.
PS: Will it broke my warranty?

Lenovo - just like IBM before them - maintains a "whitelist" of approved wireless and WWAN cards in BIOS, and if an "unauthorized" card is present, the machine will throw an error and refuse to boot.
Installing a modded BIOS would void one's warranty, theoretically speaking.

Unless you are OK with flashing a modded BIOS there is no path to installing an AC capable card.

Are there any instructions for flashing and modifying BIOS?

Not on this forum, but there are several others that are dedicated to stuff like that...
