The preferred option would be to have a discussion with the engineer or for him to suggest the strategy "Plan A" +/- target laps, "Plan B" (long stint, maybe compound change) etc.
But this depends upon the voice commands being operational on all variants of the game and it would appear to be a difficulty with PS5 particularly unless you're playing the PS4 game.
It would be easy to say "Soft", "Medium" or "Hard" / "Inters" or "Wets" on the in lap before the SC line to override any potential error with tyres.
I use a wheel with both rotary and joystick (menu navigation) control so I've never found it an issue. Only issues are where a one stop strategy becomes an opportunity for more or you change a two stop at the first stop, then all bets are seemingly off with tyre selection unless you override it.
Edit: And, I have to say, I have never lost the voice control option in F1 2021, it always seems to work perfectly, unlike previous titles, so whatever the issues were, they've improved for some of us.
