The command to disable the active technology package for a license is `no license boot module <module_type> technology-package <package_name>`. This command tells the router to disable the specified technology package, which will prevent it from being used.
The `module_type` argument specifies the type of module that the technology package is installed on. For example, `c2900` for a Cisco 2900 series router. The `package_name` argument specifies the name of the technology package to disable. For example, `securityk9` for the security technology package.
The optional `disable` keyword can be used to prevent the technology package from being automatically enabled on the next reload. If this keyword is not specified, the technology package will be automatically enabled on the next reload.
For example, to disable the active security technology package on a Cisco 2900 series router, you would use the following command:
```
no license boot module c2900 technology-package securityk9
```
This command would disable the security technology package on the router, and it would prevent the technology package from being automatically enabled on the next reload.
The `no license boot module` command is a powerful tool that can be used to manage the licensing on Cisco routers. By using this command, you can disable technology packages that you are not using, and you can prevent technology packages from being automatically enabled on the next reload.
