Setting the property wrap cells?

[IsakRein]

Is there any way to change this property via script?

Yes, see this issue that I answered to see why this works:

tableview = client.get_collection_view(url) # enter the actual url of the table view here

# you can use .get() to visualise the data structure of the page
print(tableview.get())

# .get() gets the local cached dictionary of the table view
# you can change values in it
tableview.get()['format']['table_wrap'] = True # set it to False to turn wrap off

# .set() sets the local dict to the notion server through an api call
tableview.set(path=[], value=tableview.get())
