Help Me My Laptop Died

Please don't roast me alive, I'm not super educated on this stuff. I have an ASUS TUF A15 Gaming Laptop, 15.6 inch FHD 144Hz Display, AMD Ryzen 7-6800H, GeForce RTX 3050 Ti, 64GB DDR5 RAM, 2TB SSD (bought 2021) that recently stopped booting up. Computer repair tech said it's the motherboard and he won't repair because the part comes from China and that specific shop won't buy from overseas as a policy. What should I do?
