You can now specify exactly who can change the constraints within a
query preset.
For example, you want to ensure that only "admins" are allowed to set a
preset to "everyone".
To do this, you can use the new `queryPresets.filterConstraints`
property. When a user lacks the permission to change a constraint, the
option will either be hidden from them or disabled if it is already set.
```ts
import { buildConfig } from 'payload'
const config = buildConfig({
// ...
queryPresets: {
// ...
filterConstraints: ({ req, options }) =>
!req.user?.roles?.includes('admin')
? options.filter(
(option) =>
(typeof option === 'string' ? option : option.value) !==
'everyone',
)
: options,
},
})
```
The `filterConstraints` functions takes the same arguments as
`reduceOptions` property on select fields introduced in #12487.
