My Galaxy A70 usb tethering option isn't allowing use. It's greyed out when I connect another device to it, and will not allow me to select this option. Tried Samsung Electronics support now I'm trying Koodo. Any suggestions??

Similar to what David mentioned, Samsung hides the USB configuration option within Developer Options. To enable Developer Options, select Settings > About phone > Software information. Look for and tap ‘Build number’ seven times to unlock the hidden Developer options menu. When you back out to the main Settings menu, Developer options should appear at the bottom of the list.
Select Developer options and either search for ‘USB Configuration’ or scroll down to locate it. Tap USB Configuration, a list is displayed offering various types of USB connections:
- Charge this phone
- MTP (Media Transfer Protocol)
- PTP (Picture Transfer Protocol)
- RNDIS (USB Ethernet)
- Audio source
USB debugging is also available in the Developer options menu. When enabled, it can sometimes help with problematic USB connections. This information was obtained from my ancient Samsung Galaxy S7, but the menus should be similar to the Galaxy A70.
