Final answer:
No, you cannot change the 'Grant Access Using Hierarchies' setting for Standard Objects in Salesforce OWD; it is enabled by default and cannot be modified, as opposed to the flexibility provided for custom objects.
Step-by-step explanation:
In the context of Organization-Wide Sharing (OWD), the question pertains to whether the setting 'Grant Access Using Hierarchies' can be changed for Standard Objects within Salesforce.
The answer is No. For standard objects, Salesforce does not allow the modification of the 'Grant Access Using Hierarchies' setting.
This setting is enabled by default and is designed to respect the hierarchical structure, such that users higher in the hierarchy in a role-based structure automatically have access to the records owned by users below them in the hierarchy. However, for custom objects, administrators have the option to turn this setting on or off according to their organizational sharing policies.
