User case: IdeaPad Gaming 3 15ACH6 RAM & SSD Upgrade

“I've been searching for a definite answer about this and haven't found anything. My laptop comes with 512Gb SSD on the 2242 slot and 1x16Gb RAM stick. Lenovo says that on the 2280 slot maximum SSD capacity is 1Tb and that maximum RAM is 16Gb.
BUT it says that ‘The system may support more memory as the technology develops.’ I want to install a 2Tb SSD on the 2280 m.2 slot and an extra 16Gb RAM stick and I can find no real reason why this would not be possible. Can anyone confirm that my assumptions are correct and this upgrade is possible?”
