Heavy flavour hadrons are produced in hard-scattering processes in hadron collisions before the QGP formation. The interactions of HF hadrons with the plasma lead to an azimuthal deformation of the momentum distribution, which can be studied with a Fourier expansion. The elliptic flow $v_{2}$ is the second term of the expansion and indicates an azimuthal elliptic deformation of the plasma. Its value reflects both the initial state asymmetry and the QGP hydrodynamic characteristics. Indications of non-zero $v_2$ in pp collisions have been reported from different experiments. In the ALICE experiment, the inclusive muon elliptic flow can be measured from the two-particle azimuthal correlation between muon tracks, detected in the forward rapidity region, and the SPD tracklets. A significant contribution of the semimuonic decays at intermediate and high $p_{T}$ is expected to be due to HF particles. In this contribution, the analysis strategy for the measurement of the inclusive muon $v_2$ at forward rapidity using ALICE RUN2 pp collisions data at $\sqrt{s}$ = 13 ${TeV}$ will be shown. The analysis was performed as a function of $p_{T}$, using the two-particle correlation method.
