HP does not recommend to use Third party parts as they are not tested by HP and may not be accurate. However, you could change the configuration at your own discretion and also you can check with local service center to install SSD appropriately.
Even you can reach out to our Support and our Support Engineers should be able to sort this out. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
Hope this helps! Keep me posted for further assistance.
