Most of the M.2 HATs and HAT like devices are Pi 5 only and will not connect to the 3A+, 3B, or 4B as those do not have an exposed PCIe lane (the 3 has no PCIe at all).
They are also largely M keyed.
Further, the only data signals available on the connector are for a single PCIe gen2 lane.
So if your chosen LTE modem uses all of the data lines you list it won't be fully compatible with a Pi 5. If it just uses the PCie lane it may work with a suitable adpater.
I strongly suggest you review your choice of modem. For something that will work with a Pi3 or Pi4 it needs to use interfaces that are available on those boards: no PCIe, 3.3v signals, UART, I2C, SPI, I2S, or USB via the A ports for data connection.
Or review you choice of SBC.
