How to write raw taproot transaction and apply an RBF flag?

Hi all,
I have 2 unrelated questions, but both about how to properly formulate a transaction template.

1. I'd like to know how to add an RBF indicator to the transaction (and any relevant details).

2. I'd like to know how to create a taproot transaction template I can use

Here's my current standard raw transaction template I use;

Code:

createrawtransaction \
'[{"txid": "txid1", "vout": vout1},
{"txid": "txid2", "vout": vout2},
{"txid": "txid3", "vout": vout3},
{"txid": "txid4", "vout": vout4}]' \
'{"address1": Amount1,
"address2": Amount2,
"address3": Amount3,
"address4": Amount4}'

If there are any resources you can point me to, please let me know.

The software I am using to create, sign, and send transactions is Bitcoin Core QT (console)
