It is currently . Unlike the early "V1" unpatched consoles from 2017–2018, which have a hardware-level vulnerability, the V2 (Mariko) model released in 2019 is patched and requires a physical modchip to run custom firmware. nintendo switch v2 softmod
The story of the V2 softmod doesn't have a clean ending because it eventually converged with the hardware solution. This was a "hardmod," not a "softmod
More importantly, they refined the software side. The Mariko CPU is still secure, so we cannot patch it live. However, we can patch the storage . It is currently
