Could be, but it is unlikely with a lens designed specifically for a camera system also targeted to semiprofessional videographers, which also seems to have a timelapse function built in. They would likely not include it if it caused extreme wear in a standard configuration - the last feature a manufacturer wants to include is one that prematurely breaks equipment without a way to blame it on the user (which they could if they made people use external intervalometers etc...). Doubly not on a budget priced camera where the cost of arguing with entitled customers will eat into their margin.
About stopping that behaviour anyway:
This might or might not apply to the GF-7 specifically, but many DSLM designs will not meter wide open if you set them to any exposure mode that has a manually set aperture (M or A at the very least).
Alternatively, if you can get away without autofocus, use an adapted manual lens - the camera has no control over the aperture that way, which will stop it from operating it with absolute certainty.
Alternatively - but this COULD ACTUALLY CAUSE EQUIPMENT FAILURE or raise power consumption significantly, depending on camera/lens design: Check if there is a DOF preview feature assignable to a button, and tape that button down.
