How can I tell if the M.2 (E-Key) slot on my MB meant for wifi has two PCIe Gen2 x1 lanes?

I have a Dell Inspiron 3880 running Debian server. It has an M.2 slot that had a Wifi/BT card in it but I took it out. I want to install a M.2 Accelerator with Dual Edge TPU ( https://coral.ai/products/m2-accelerator-dual-edgetpu ) on it but it requires an M.2 E-key (with two PCIe Gen2 x1 lanes) . I checked dmidecode and this is the output: # dmidecode 3.4 Getting SMBIOS data from sysfs. SMBIOS 3.2.0 present. Handle 0x0025, DMI type 9, 17 bytes System Slot Information Designation: SLOT2 Type: x1 PCI Express Current Usage: Available Length: Short ID: 2 Characteristics: 3.3 V is provided PME sig
