Is it possible to configure a rotary switch so that
Off to ground and bypasses the meter
1 to tube 1 current measurement
2 to tube 2 " "
I don't know how rotary switches are configured but i have some.

Yes, it's just a matter of being able to make and break what needs to be.
Break the cathode from ground and connect it to the top of the grounded meter while doing nothing to the other side.
Then re-make that connection from that cathode to ground while breaking the other cathode from ground and connect it to the top of the grounded meter.
Then back to neither cathode being connected to the meter but both are connected to ground.
Doable with the right switch.
I'm liking the 2 switch option but only because it's easy.

First things first, there's a good chance the meter will have no impact on sonics. Measure it's resistance before going to the trouble of adding a switch. It might be only a few ohms. If it turns out that's not the case, there's no reason to switch it out of circuit when it's not needed. Just leave it in series with the cathode and add a switch in parallel to bypass it to ground. Nothing more is needed.

power tube current without at least 2 switches, 1 switch for bypass?
For that you'll need a two pole, three position rotary ("L - Off - R"). Contacts should be non-shorting, make-before-break.
