At the time the product brief was originally written, it was anticipated that there may be a need to support graphics mode in certain configurations (if it were deemed to be needed for that config). There is no indication in the product brief that this would be end-user configurable. Graphics mode was intended for situations where it might be needed to support particular features of the GRID product offering, and/or support particular OEM system configurations. As already pointed out, where there is discussion of actual modification of the mode in-situ, the P40 is explicitly excluded from that discussion.
During subsequent product development and the lifecycle to date, this feature has never been needed. Therefore all P40 are shipped in Compute mode.
Tesla products are only intended to be sold by certified partners, and then only in systems that are certified to support those products. We don’t support Tesla products for use in a platform that was not certified by the OEM for that specific Tesla product. For OEM supported configurations, the specific product offerings and supported configurations are defined by the OEM and are not necessarily end-user modifiable.
No OEM has ever offered this product with support for Graphics mode, therefore placing the product into graphics mode would be an unsupported configuration across the board. Due to that, no tools have ever been developed or provided to manage the configuration, since there is effectively only one supported configuration (with respect to the mode).
If you purchased the Tesla product from a certified OEM in a certified configuration, you also have the option to address your support concerns with that OEM or the channel through which you acquired the product.
