Don't know that we want to advertise it too much, but the download page includes a service manual which has more information about disassembly although I'm a bit of a worrier and am still a little concerned about some customers who may get into trouble trying to follow it. If necessary, consider finding some qualified help if there are any concerns about getting into trouble trying this.https://dlcdnets.asus.com/pub/ASUS/GamingNB/G513RC/E19513_G513R_G713R_SM_WEB.pdf
Most people may or may not be aware of it, but connectors on the notebook are fairly fragile and can be broken, so you want to be careful with that since there is no easy way to fix broken connectors.
Don't usually repair notebooks myself, but looks like there is a metal piece securing the battery connector which you need to slide in the direction of the arrow indicated in the service manual to 'unlock' it and allow you to lift up the battery connector.
If it can be done safely, it's a good idea to unplug the battery connector after opening up the unit just in case something metal is accidentally dropped and zaps something important on the motherboard.
The service manual is showing two M.2 SSD connectors, but if you check the ASUS download page, there aren't any Win10 drivers posted for this model, so don't know that everything will go smoothly regarding Win10 if you want to prepare for that possibility and start considering other options.https://rog.asus.com/us/laptops/rog-strix/rog-strix-g15-2022-series/helpdesk_download/
