-The [AVD-DS-0016](https://avd.aquasec.com/misconfig/dockerfile/general/avd-ds-0016/) check is disabled for this scan type, see [issue](https://github.com/aquasecurity/trivy/issues/7368) for details.
+#### Disabled checks
+
+The following checks are disabled for this scan type due to known issues. See the linked issues for more details.
+
+| Check ID | Reason | Issue |
+|----------|------------|--------|
+| [AVD-DS-0007](https://avd.aquasec.com/misconfig/dockerfile/general/avd-ds-0007/) | This check detects multiple `ENTRYPOINT` instructions in a stage, but since image history analysis does not identify stages, this check is not relevant for this scan type. | [#8364](https://github.com/aquasecurity/trivy/issues/8364) |
+| [AVD-DS-0016](https://avd.aquasec.com/misconfig/dockerfile/general/avd-ds-0016/) | This check detects multiple `CMD` instructions in a stage, but since image history analysis does not identify stages, this check is not relevant for this scan type. | [#7368](https://github.com/aquasecurity/trivy/issues/7368) |
