BTT eddy config with G28 called recursively, and calibration failed.
Oh, that's why! Sorry for being negative for the mounts from the repo(I thought it is compatible for the EVA3, but yeah the naming kinda misleading.)
Nevertheless, thanks for the information and the contribution!

BTT Eddy USB
@Qui1zy Here's some workaround to use BTT Eddy on the VC3.1, from my recent implementation.
My machine:VC3.1-500, BTT Eddy act as a probe and Z-endstop.
Perquisites: You need to update klipper tot the latest commit, no matter for a existing ratos or new install, the native support of BTT Eddy was implemented into klipper this October or November-ish. You can do this by ratos update manager.
Most of the steps below can be found instructions at BTT Eddy repo, to summarize:
1. Make and flash the firmware to Eddy.
2. Mount the Eddy to the EVA carriage.
3. Edit printer.cfg, comment out the [probe] and probe-related includes, as @EODesigns suggested. Then depends on the usage of Eddy, copy the configuration to user override section in printer.cfg from Eddy repo.
4. Comment the [gcode_macro G28］section of the Eddy macro.
4.Do LDC_CURRENT_CALIBRATE
5.Do probe_calibration
When mounting Eddy to EVA carriage, MAKE SURE that Eddy probe are 2-3mm above nozzle.
There is a discussion for my G28 and calibration problem, and solutions about these two, you can take a look, see if helps.

BTT eddy config with G28 called recursively, and calibration failed.
To wrap up the whole journey and to help other that looking for solutions:
1. Make sure the BTT eddy is "2~3mm ABOVE" the nozzle, in my testing, you can still have successful calibration up to ~5mm-ish.(Creds to @EODesigns )
2. DO NOT use the probe mounts from the BTT official repo(https://github.com/bigtreetech/Eddy/tree/master/3D/EDDY_PRINT_PARTS/EVA3), this mounts will lift the probe too high, causing GUARNTEE failure when doing "PROBE_EDDY_CURRENT_CALIBRATE_AUTO CHIP=btt_eddy".
3. To solve the above problem, I design a height-adjustable BTT eddy probe mount, from remixing existing induction probe mount, which you can find here(https://www.printables.com/model/1124920-btt-eddy-adjustable-probe-mount-for-ratrig-eva-3-s)
Hope anyone find this wrap-up can help.

Oh okay, so then I guess we're wrapping up, I also commented out the G28 portion, so the recursive call don't bother. Thanks for the lookups!

Turns out, the probe mount that BTT provide will mout the probe too high, the initial height was around 15~17mm-ish.

Dunno if you have any experience with the G28 problem, can't tell if the G28 override part from BTT is necessary.

Though I may not reach the 2~3mm above the nozzle, instead i got 5mm-ish above the nozzle.
After a test-cal, the proceduce finish sucessfully! Really appreciate the suggestions!

Well, got really good progress. Following your suggestion, I remix the original 8mm probe mount into height adjustable eddy mount.

Just eyeballing a safe distance has achieved, I use the BTT-provide mounting brackets model to do the job.
Maybe some modification to make bracket adjustable is needed. I'll get you latest info about trying to adjust the eddy 2-3mm above the nozzle.

Yeah, I also uses Eddy to home Z. As you mentioned, I commented any [probe] related includes and statements before all the hassle happens.
How about your experience on calibrating Eddy? Because this part gives me the most headaches.
