[1] Bring your laptop in the middle of a forest/dessert then create your wallet.
It's silly, but you get the idea: move to a place where there's no structure within a few meter radius around you.

[2] Not sure if this will work (theoretical):
Buy another HDMI cable, do not use VGA/DVI,
lay it down in a different direction of your currently installed cable, do not connect it yet.
When you're ready to create the wallet, change the position/location of your PC & monitor and switch the cables.
(This way, the hacker might lose the signal, if not, might become too fuzzy and will take a few sec to re-calibrate)
Then copy you SEED and create the wallet as fast as possible.

For trojan, aside from Antivirus.
just create the wallet in an air-gap machine and transfer the already created wallet file to your online machine.

Is it possible to do this, for example, print a seed phrase right away so that it does not show on the screen?

Electrum and other wallets (except Core):
You will have to re-enter the SEED in the wallet creation wizard for verification which will defeat its purpose.
Besides, printer's signal or your keyboard strokes can be hacked over the air too.
