Despite the increasing prevalence of radio-loud (RL) sources at cosmic noon, our understanding of the underlying physics that governs the accretion disc outflows in these particular sources and its dissimilarity with radio-quiet (RQ) quasars remains somewhat limited. Disentangling the real impact of the radio-loudness and accretion on the outflow parameters remains a challenge to this day.We present 10 new spectra of high-redshift and high-luminosity quasars and combine it with previous data at both high and low redshift with the aim to evaluate the role of the feedback from RL and RQ AGN. The final high-redshift (1.5<~z<~3.9) high-luminosity (47.1<=log(L)<=48.5) sample consists of a combination of 60 quasars from our ISAAC and the Hamburg-ESO surveys. The low-redshift (z<=0.8) sample has 84 quasars with optical and Faint Object Spectrograph (FOS) reanalyzed data. We perform a multicomponent analysis of optical and UV emission line profiles along the quasar main sequence, and provide a relation to estimate the outflow main parameters (mass rate, thrust and kinetic power) in both the BLR and NLR through the analysis of the [OIII]{lambda}5007 and CIV{lambda}1549 emission lines. Spectrophotometric properties and line profile measurements are presented for H{beta}+[OIII]{lambda}{lambda}4959,5007, SiIV{lambda}1397+OIV]{lambda}1402, CIV{lambda}1549+HeII{lambda}1640, and the 1900{AA} blend. High-ionization lines as such CIV{lambda}1549 and [OIII]{lambda}5007 usually present a significant asymmetry towards the blue especially in radio-quiet sources that is strong evidence of outflow motions. In the ISAAC sample, 72% of the quasars where [OIII] is clearly detected present significant outflows, with centroid velocity at half intensity blueshifted to values greater than ~250km/s. Radio-loud quasars tend to present slightly more modest blueshifted components in both the UV and optical ranges. The behavior of [OIII]{lambda}5007 mirrors the one of CIV{lambda}1549, with blueshift amplitudes between the two lines showing a high degree of correlation that appears unaffected by the presence of radio emission. In contrast to low redshift, both RL and RQ AGN outflow parameters at high luminosity appear in the range needed to provide feedback effects on their host galaxies. Both high- and low-z RL quasars exhibit smaller outflows compared to RQ, suggesting a potential role of radioloudness in mitigating outflow effects. Nevertheless, the radio-loudness effect on the AGN feedback is much less significant than the one of accretion that emerges as the main driver of the nuclear outflows.
