Miivii Apex Dual Orin Storage Capacity Problem!

Hello, Dual Orin PC has 64 GB capacity memory in different systems under Master and Slave. I installed and installed 2x 1 TB SSDs to expand this memory. My question is that I am installing ROS, Perception, Sensor Driver etc. or Program on this system and I will have a capacity problem. 1 TB SSDs capacity problem and how can I transfer system documents in internal memory. Or how can I use 64 GB capacity + 1 TB SSD disk as a whole. have a nice day,
