Many thanks to Sébastien MARQUE for the suggestion `nmcli radio all off`. This resolves the problem. For me, I don't need to wait for nvidia to no longer be in lsmod before I can start it again.
This is with a Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31), Intel Corporation UHD Graphics 620 (rev 07), and NVIDIA Corporation GP108M [GeForce MX150] (rev a1), on an up-to-date Debian 10 using nouveau drivers if I'm not mistaken (I tried every possible setup until something worked to run Parkitect a few weeks ago, not sure what the current setup is, just that the nvidia-detect command doesn't exist and I have to prefix primusrun and add -force-opengl). If I can help by providing details about my setup or by trying something, please let me know what commands to run -- via lgms.nl/email since I expect I'll be receiving spam on the sending address before too long which means I'll have to block it. Best, Luc
