Hi @liorko87, bech32 is the default, but the getnewaddress help explains how you can set the address type:

$ bitcoin-cli help getnewaddress
getnewaddress ( "label" "address_type" )

Returns a new Bitcoin address for receiving payments.
If 'label' is specified, it is added to the address book 
so payments received with the address will be associated with 'label'.

Arguments:
1. label           (string, optional, default="") The label name for the address to be linked to. It can also be set to the empty string "" to represent the default label. The label does not need to exist, it will be created if there is no label by the given name.
2. address_type    (string, optional, default=set by -addresstype) The address type to use. Options are "legacy", "p2sh-segwit", and "bech32".

You can also set it for your node as a configuration option on the command line when starting the node or in your bitcoin.conf file:

$ bitcoind -h | grep -C1 "What type of addresses to use"
  -addresstype
       What type of addresses to use ("legacy", "p2sh-segwit", or "bech32",
       default: "bech32")
