Seems oddly bait and switch given RFC6979 advises to use deterministic nonce (which secp256k1 has ecdsa support for and Coldcard Mk4 uses?) while folks are trying to redo nonce impl’s for Schnorr signing because DN
https://github.com/randombit/botan/issues/2939
https://github.com/BlockstreamResearch/secp256k1-zkp/issues/172
https://github.com/bitcoin-core/secp256k1/pull/1140
Btw can also do deterministic build of Coldcard firmware and flash
