I do not know but I think that option is available in that version " please check it."
also, you must update your electrum version to the latest version. read about Critical Electrum vulnerability ---->

about segwit read this
For segwit transactions it depends on the transaction.
A typical transaction of one input, two outputs is 226 bytes legacy, 166 vbytes P2SH-P2WPKH segwit (27% less), 141 vbytes pure bech32 P2WPKH segwit (38% less).
If you have many inputs, the savings are larger (and less for many outputs). For 10 input, 1 output legacy is 1515 bytes, 953 vbytes P2SH-P2WPKH (37% less), and 722 vbytes P2WPKH (52% less).
Multisignature transactions benefit even more. Multiinput 2 of 3 multisignature transactions in bech32 P2WPKH segwit are 75% smaller.
