Bedrock Model access modifications

Question

In the Bedrock model access screen, some of my active models that have been granted access are grayed out. I cannot disable them.  Can  someone help me understand what is going on? I am able to use these models in my client but cannot disable them. Specifically I cannot disable the following since they are grayed out -
Titan Embeddings G1 - Text
Titan Text G1 - Lite
Titan Text G1 - Express
Titan Text G1 - Premier
Mistral 7B Instruct
Mixtral 8x7B Instruct
Mistral Large

TIA

Hello.

As stated in the documentation below, some models, such as Amazon Titan, cannot be disabled once enabled.  
https://docs.aws.amazon.com/bedrock/latest/userguide/model-access.html#model-access-remove  
> You can't remove access from Amazon Titan models, Mistral AI models, or from the Meta Llama 3 Instruct model.

Thanks for pointing that out, I wish I knew this before I enabled them. Now I have no way to remove them from my list of models that I programmatically determine as available.

You can remove access to these models through an identity-based policy that denies access to running inference on a specific model. See the documentation [here](https://docs.aws.amazon.com/bedrock/latest/userguide/security_iam_id-based-policy-examples.html#security_iam_id-based-policy-examples-deny-inference) for more details.
