Can you switch from connecting the RPi from pifi access point to an actual router access point

Question

So for a robotics project I have in mind I'm trying to create an access point on my rpi so that I can directly ssh into it without using wifi from another router. But the problem is that I'm not sure whether I can switch from the pifi access point back to my home router. I want to be able switch from my pifi access point to my router because I'd need to download libraries online. I tried using the Ubiquity Robotics rpi ubuntu image that has ROS preinstalled and I tried tinkering with the pifi thing in it but I couldn't use the internet even with an ethernet cable connect to the router. So I wanna know if its possible to switch from pifi access point to a router that i have at home, and if it is, then how do I go about doing it. Thanks in advance.

Please let know if i should elaborate a bit more.

I don't know what a pifi access point is but it is not necessary to switch anything. You can have an access point on the Raspberry Pi and also be connected with a WiFi client connection to your internet router. How to do it you can look at Access point as WiFi router/repeater, optional with bridge.

If you like to simplify the setup you can purchase an additional USB/WiFi dongle and use two physical WiFi interfaces. You can look at Access point as WiFi router/repeater with additional WiFi-dongle doing this.

If you really have to switch the access point for some reason you may have a look at Automatically Create Hotspot if no Network is Available.
