I'm not sure I understand you 100% but if you are asking about unprovisioning a mesh device using nRF Mesh SDK , please have a look at the button_event_handler() in light switch server example. When you press button 4 , the provisioning data will be erased and all configuration information in flash will be erased.
In sample example of nrf52 for light switch server handled for RTT pressing button4 from serial terminal it is getting unprovisioned.I need to unprovision by pressing the button on the hardware manually.How to give input via button instead of RTT.plz suggest your answer

If you have a look at the code inside app_rtt_input_handler() to handle RTT input, you can find that it in turn will call button_event_handler(). So in the light switch or light_lc example if you press button 4 on the board, it's the same as when you input '4' in RTT. Both of them will end up executing this code:
case 4:
{
/* Clear all the states to reset the node. */
if (mesh_stack_is_device_provisioned())
{
#if MESH_FEATURE_GATT_PROXY_ENABLED
(void) proxy_stop();
#endif
mesh_stack_config_clear();
node_reset();
}
else
{
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "The device is unprovisioned. Resetting has no effect.\n");
}
break;
}
So I'm not sure why you don't get the same effect when you press button 4 on your board, what's the issue here ?
Ok, so you based your application on light_lc example. And in that example the buttons are not handled.
You would need to have a look into the light switch server example. In that example we include the simple_hal.c module to handle the buttons. Note that we don't use nrfx_gpio in that example but use simple_hal.c instead. You need to include simple_hal.c to your project just like in the light switch example. Then you need to call ERROR_CHECK(hal_buttons_init(button_event_handler)); inside intialize() function. Please refer to the code inside light switch server example.
