White List cannot be changed when advertising/scanning:

• any advertising filter policy uses the White List and advertising is
enabled,
• the scanning filter policy uses the White List and scanning is
enabled, or
• the initiator filter policy uses the White List and an
HCI_LE_Create_Connection or HCI_LE_Extended_Create_Connection
command is outstanding.
