Eh, what? Adding greater capacity SSD has nothing to do with the CPU, it's more to do with the motherboard. Even if it's a laptop, it IS possible to adding a higher capacity SSD, or another SSD depending of availability of a compatible slot. Is yours a laptop or some sort of Ryzen 4700S kit?
For example, my Ryzen 9 3900X setup (with X570 Aorus Xtreme) has a good number of SSDs and HDDs (4TB + 2TB + 2x 1TB SATA SSDs, with 2x HDDs in the mix). I also run my OS (and essential programs) off a 256GB NVMe M,2 drive. Even my recently acquired laptop with an R7 5800H which came with a 1TB M.2 NVMe PCIe SSD can be upgraded with another NVMe PCIe SSD (I've ordered a WD 2TB M.2 NVMe PCIe SSD for the remaining spare/empty NVMe slot on the laptop.
