Is the parameter "disable_peiv_optimisation" set to "false" in the whole process?

Hello, I am very interested in your work and your work has achieved good results.
However, I still have some questions. Is the parameter "disable_peiv_optimisation" set to "false" in the whole process? if it is such as "if not disable_peiv_optimisation" This judgment is a little redundant.
In addition, one of your important innovation points is "v", may I ask that the testing stage of the meta-training and the final verification stage need to be updated throughout the process?
