Modifying the value of this attribute shall not be performed

the current VNF's on-boarded VNF package, the values of attributes

Additional VNF-specific attributes that provide the current values
of the configurable properties of the VNF instance.
These attributes represent values that are stored persistently in
the VnfInstance structure and that correspond to configuration
parameters of the VNF instance.
Modifying these attributes affects the configuration of the VNF
instance either directly (if the VNF instance is in INSTANTIATED
state at the time of the modification) or as part of the subsequent
VNF instantiation operation (if the VNF instance is in NOT_INSTANTIATED
state at the time of the modification).
Configurable properties referred in these attributes shall be declared
in the VNFD.
The declaration of configurable properties in the VNFD can optionally
contain the specification of initial values.
ETSI GS NFV-SOL 001 specifies the structure and format of the
VNFD based on TOSCA specifications.
VNF configurable properties are sometimes also referred to as configuration
parameters applicable to a VNF. Some of these are set prior to instantiation
and cannot be modified if the VNF is instantiated, some are set prior to
instantiation (are part of initial configuration) and can be modified later,
and others can be set only after instantiation. The applicability of certain
configuration may depend on the VNF and the required operation of the VNF at
a certain point in time.
These configurable properties include the following standard attributes,
which are declared in the VNFD if auto-scaling and/or auto-healing are
supported by the VNF:
- isAutoscaleEnabled: If present, the VNF supports auto-scaling. If set
to true, auto-scaling is currently enabled. If set to false, auto-scaling
is currently disabled.
- isAutohealEnabled: If present, the VNF supports auto-healing. If set
to true, auto-healing is currently enabled. If set to false, auto-healing
is currently disabled.
This attributeThese attributes can be modified with the PATCH method.

Modifying the values of these attributes has no direct effect on the VNF instance;
