I'm no SLURM expert, but a jobfile like this should work:

#SBATCH --job-name=N2n4

#SBATCH --output=N2n4-CUDA.txt
#SBATCH -N 1 # number of nodes with the first GPU
#SBATCH -n 2 # number of cores

#SBATCH hetjob
#SBATCH -N 1 # number of nodes with the second GPU
#SBATCH -n 2 # number of cores
#SBATCH --gres=gpu:GeForceRTX2070:1
...
I can't test (we haven't GPU nodes), but that's how it should work,
according to (my understanding of) the docs. Maybe someone more
experienced can refine it.
No... it doesn't work...

Have you tried defining it as heterogeneus job?
https://slurm.schedmd.com/heterogeneous_jobs.html
#SBATCH hetjob
for new SLURM versions or
#SBATCH packjob
for older ones

Hi,
Today, doing some tests, I have not got a solution to write a submit
script that requests 2 different GPUs on 2 different nodes. With this
simple script:
#!/bin/bash
#
#SBATCH --job-name=N2n4
#SBATCH --output=N2n4-CUDA.txt
#SBATCH --gres=gpu:GeForceRTX3080:1
#SBATCH -N 2 # number of nodes
#SBATCH -n 4 # number of cores
#SBATCH --partition=cuda.q
module load cuda/11.2
sleep 100
mpirun /home/caos/druiz/samples-SLURM/OpenMPI/mpihello-3.0.0
I get a parallel MPI job in two nodes, two process in each node and
one
GeForceRTX3080 in each node. However, if I want to request 2 different
GPUs, I can't write "#SBATCH --gres=gpu:GeForceRTX3080:1,
--gres=gpu:GeForceRTX2070:1" because line "#SBATCH --gres=" is for
each node and, then, a line containing two "gres" would request a node
with 2 different GPUs. So. is it possible to request 2 different GPUs
in 2 different nodes?
Thanks.
