I bought a computer where a secure boot module was optional I saved money by opting out of secure boot If I needed it I could add it later But I boot NetBSD from USB stick to RAM-based filesystem (e.g., mfs ,tmpfs), there is no internal HDD or SSD I do not boot with "secure boot enabled" because the computer does not have a secure boot TPM
