It's this will be work?

    // Initialize the Bond Manager.
    bond_init_data.flash_page_num_bond     = FLASH_PAGE_BOND;
    bond_init_data.flash_page_num_sys_attr = FLASH_PAGE_SYS_ATTR;
    bond_init_data.evt_handler             = bond_evt_handler;
    bond_init_data.error_handler           = bond_manager_error_handler;
    bond_init_data.bonds_delete            = true;

    err_code = ble_bondmngr_init(&bond_init_data);

It should be possible to disconnect the link, delete all bonds and then restart advertising when a button is pressed in a specific way. Take a look at this question for slightly more details.
