What Minolta cameras meter off the film plane and when do they do it?

I have some IR gel that I'm planning on putting a piece of in the film gate on one of my Minolta cameras, so I'll be able to see through the finder and use the meter.
I have several SR-ts but I'd prefer something lighter, like my XD-7 (XD-11 or XD) or X-700.
That made me think that the gel might become a problem with off the film plane metering. It wouldn't be good to meter off the IR gel probably.
I can't find a satisfying conclusive answer anywhere, so:
Does do either of the aforementioned cameras meter off the naked (not the shutter) plane at any point or mode other than flash TTL metering (only X-700)?

None of the XD, XG, or XK cameras do. None of the X-370/X300 variants do. As far as I know only the X-700, X-570, and CLE do.

The best way to photograph with IR films is to shoot with the sun behind you [back lit is a waste of film], meter at box speed, then use the filter factor to adjust the light meter reading. Simple, easy to do and it works. Getting fancy is a way to waste both time and film.

What’s fancy?

One of the greatest IR shots I ever took was towards the sun down a rain wet street.
Absolutely no rules.

Even if there’s is no IR light, just make it yourself.
The meter is only a guide. The exposure depends hugely on the humidity and the amount and depth of shade.
Shade on a sunny day is blue as it’s lit by the blue of the sky. But it still has quite a lot of IR in it.

If you use a polarizer, the exposure isn’t cut quite as much as your meter would have you believe.
