It turns out that this actually regressed some qualcomm modems because modem-manager started to use some special netlink sockets that were not enabled in the 5.4 kernel.

To have that we need (see LP: #1998194):

CONFIG_QRTR=m
CONFIG_QRTR_SMD=m
CONFIG_QRTR_TUN=m
CONFIG_QRTR_MHI=m

in the 5.4 kernel. However, this might not be easy according to some discussion I had. Would it be possible to revisit this backport?
