Not quite. They're experimenting with commodity hardware to provide additional experimental functionality on missions, not to replace the core mission hardware.
For instance the mars helicopter, Ingenuity, was effectively an expendable part of the Perseverance rover mission. Even if it never took off they'd still consider the overall mission a success. That it has worked so well despite using commodity hardware has been a nice surprise and might result in NASA using more of it, but the Perseverance rover still used proper rad-hardened chips and other specialised spacecraft components.
They're also definitely not using commodity hardware and fail-fast-fail-often on crewed aircraft.
